Canon EF 28-135mm f/3.5-5.6 IS USM Standard Zoom Lens for Canon SLR Cameras

I bought this lens four years ago and have shot around 6,000 photos with it (4000 digital, 2000 35mm). Autofocus is very fast and quiet, which is typical of the Canon USM lenses. I would not recommend a Canon lens that does not have the ultrasonic motor (USM) focusing. Optics are sharp throughout the focusing range.

The lens is fairly heavy and after a few months of use, you will likely find that the weight of the glass is enough to make the lens telescope out when it's around your neck. If you want a compact lens that will let you take great pictures in a wide range of settings, this is probably the best lens you could get for a Canon camera. If you're a pro, you'll probably have a backpack full of lenses and you're not reading this anyway, so I'm not talking to you. If you want something you can sling over your shoulder and not think about when you take the kids to Disney World, get a cheaper, lighter lens.

The Image Stabilizer (IS) makes the lens a lot more expensive (some lenses are offered with and without it), so you should know what you're paying for. Some notes about the Image Stabilizer:

- The image stabilizer itself is basically a spinning lens element (piece of glass) that acts as a gyroscope. When the lens moves slightly, such as camera shake caused by your pulse, the gyroscopic element stays put while the other elements move. Because the gyroscopic element is no longer in line with the other elements, it effectively bends the light just enough to compensate for the lens moving.

- Having the IS feature does not mean that you can take crisp photos with a 1/20 sec exposure while jumping on a trampoline. What it means is that you can often get away with not carrying a tripod in normal lighting, and in low light when your photos would be very blurry (assuming you're not using really fast film), the IS will make the images significantly less blurry. An obvious corollary is that you can avoid using a flash in many situations when a flash is undesirable or prohibited.

- The rule of thumb to get crisp photos without image stabilization is that your shutter speed should not be longer than 1 over your focal length. So if you are taking a picture zoomed in at 135mm, your shutter speed needs to be 1/135 sec or faster, and since no camera I know of has a 1/135 setting, that means going up to 1/160 sec (on cameras with stops in 1/3 increments) or faster. The image stabilizer means that you can go 2 f-stops slower than you normally could using the rule I just explained. So if you're shooting at 135mm and you have the IS switched on, you can shoot at 1/40 sec instead of 1/160 sec. That means four times as much light goes past the shutter, or that you can get the same quality results with 1/4 of the ambient light you would normally need.

- There are some times when you SHOULD NOT use the IS feature. You should definitely not use it if you are in a car, on a roller coaster, if you are walking, or in any other situation where the camera is moving or vibrating a lot. You will get blurrier than normal images because the gyroscopic element is constantly moving all over the place, trying to prevent the image from moving. Only have IS switched on when you are using the camera in a normal, stationary, handheld manner. You should also not use IS when you are using a tripod, or when you have the camera resting on a vibration-less surface for an image. The reason is that the gyroscopic element will be spinning even though it's not needed, and while this isn't really bad, the motion could decrease photo quality (I've never noticed this, but this is what Canon claims), and it is unnecessarily using battery power.

- Finally, not all of Canon's IS lenses use the same IS technology; many of the more expensive and newer lenses are better, but it was hard enough for me to come up with what this lens cost--it'll be awhile before I can rationalize three times as much for an upgrade.

One last note about third-party lenses, in case you're thinking about it. I know the price may be compelling but there genuinely does seem to be major quality differences, and while all Canon EOS lenses work will all Canon EOS cameras, no matter how many years apart they are in design, it has happened several times that even the best of the third party lenses (Sigma, some others) do not function properly with new Canon cameras. I happily buy knock-offs with other things, but not with lenses, flashes, or other camera components that actually communicate with my camera.

Canon EFS 55-250mm f/4.0-5.6 IS II Telephoto Zoom Lens for Canon Digital SLR Cameras

I had owned Canon Digital Rebel XSi 12.2 MP Digital SLR Camera with EF-S 18-55mm f/3.5-5.6 IS Lens (Black) for about a year and I have discovered that the standard lens that it came with was rather limited in terms of what sorts of shots I was able to take, especially when it came to taking pictures of distant object. I was not willing to spend too much money on any of the higher end professional or prosumer lenses. I needed something that would take decent photographs under the normal shooting condition, something comparable to the performance of the standard lens. I also wanted image stabilization, as I had come to appreciate how important it was for making low-blur shots. This Canon EF-S 55-250mm f/4.0-5.6 IS II telephoto zoom lens fit that description perfectly, and over the time I've owned iy it has met or exceeded all of my expectations.

The lens, as can be expected, shoots good high-zoom pictures, especially in broad daylight. The image stabilization greatly helps in lower light condition as it eliminates a lot of the blur. However, I have not had much success with using this lens at night, even with really long exposure while using a tripod and a remote control. In my experience I got the best result when using this lens for shooting (relatively) nearby objects at high zoom. This would give me a really large contrast and the pictures that I got that way are among some of the best I ever shot.

This is also a fairly heavy lens, especially if you are not used to interchangeable lenses, so you need to plan in advance if you are going to use at a particular shooting situation or not. I discovered that it just fits perfectly in my regular sized DSL camera bag. Also, if you are using more than one lens at the shooting session be very careful when exchanging the lenses. I recommend always trying to find a flat surface on which you can lay down any one lens at a time.

Whether you are interested in taking close-ups of distant objects or creating some interesting artistic effects, this is a perfect lens to invest into after you've gotten used to taking pictures with SLR cameras.

Canon EOS 60D 18 MP CMOS Digital SLR Camera (Body Only) + WSP Mini tripod, Cleaning set

I was using a Nikon D90 and decided to change to Canon... the 60D was my choice.

I've been playing with this camera since 2 months ago and I just love it! I can only compare it with my old Nikon 90 because its the only DLSR I had in the past...

I know that to compare these two cameras is not fair, but this is my personal situation.

The build of the camera is great, being able to move the screen is also a great option. The quality of the pictures is awesome, the adjusts you can make... everything is great, I just love this camera.

Before buying this camera I saw lots of video reviews, and people sometimes were very hard with this camera saying that the shutter was noisy, or things like that... BUT if you come from a Nikon D90 or lower, you will love this camera.

I dont have a compaint so far... everything works perfect, I even had a photoshoot where we had a little rain.. and the weather seal worked perfect...

I'm not a pro, but I recommend this Camera for sure.

Canon EOS 50D 15.1MP Digital SLR Camera

SECTION 1: WHO IS THIS REVIEW FOR

This review is close to 10 pages long because it was written for people who are not proficient with the terms and concepts used in the DSLR world. If you are a proficient DSLR user then I would recommend that you check one of the much shorter reviews here or dpreview. For example, you already know what vignetting is and therefore understand the importance of the new lens peripheral illumination correction feature. However, a new DSLR buyer does not know what this means and this is why I therefore explain what each feature really is so these people can then decide if the feature is really important to them.

If you have not done so as yet, be sure to also check out my reviews of the Canon 7D and Canon 40D as well.

SECTION 2: INTRODUCTION

It has been just over a year now since I purchased my Canon 40D. At the time, I was just beginning to take my photography really serious. Since then, a lot has changed. I have now become a semi-pro. I still have my full-time job as an IT Manager here in Miami. However, I do a lot of photography work, especially events, on the weekends.

I really love my 40D but as I started doing more and more professional work I realized three things:

1. I needed a second camera body

2. I needed a camera with a more professional focusing system.

3. I needed a camera with even higher ISO performance

It was rumored back then that the replacement for the Canon 5D would be out in the first quarter of 2008. I decided to wait for it. However, when the time came there was no news from Canon about the 5D replacement. This was back in March 2008. The Nikon D300 had now been out for a while by then. I thought about buying it but I decided to wait until it was fully reviewed by dpreview as I wanted to see if Nikon had really finally addressed the high ISO performance issues. I ordered it one day after it was reviewed by Phil Askey on dpreview.

Since then, I have been using both the Canon 40D and the Nikon D300. I know it is a bit of a strange combo. People are always surprised when they see that I am using a Canon and a Nikon together.

I took all three cameras - Canon 40D, Canon 50D and Nikon D300 - over the weekend to the Miami Seaquarium to see how the new Canon 50D compared with both of them.

SECTION 3: NEW/CHANGED FEATURES

A. High-resolution LCD Screen

The LCD screen is still 3 inches. However, Canon has now increased the resolution from 230,000 dots to 920,000 dots which is the same as that found on the Nikon D300. Of course, this makes it a lot easier to check images on playback to see if they are sharp and in focus. More important, however, is the fact that Canon added a two layer anti-reflective coating which makes it way easier now to review images in bright sunlight. It is a lot easier to review images on the Nikon D300 than the Canon 40D. However, the Canon 50D definitely surpasses the Nikon D300 when reviewing images in bright sunlight.

B. 15.1 Megapixel CMOS Sensor

I think the MP increase is the biggest surprise to me since Canon has always been conservative when it comes to this. However, this increase now seems to be the trend as the new Canon EOS 5D Mark II has gone from 12 MP to a whopping 21 MP. I was always puzzled by the fact that the baby Canon Rebel had more MP than its big brother.

I can clearly see the difference in the resolution of the images produced by the 15.1 MP Canon 50D and those from the 10 MP Canon 40D. For a casual shooter this is not a big deal. However, for professionals shooting events this is really useful. Whenever I shoot an event I try not to turn it into a photo shoot. People are there to have fun. That is the first priority. I need to be able to get my shots fast. Many times this means getting the shot and then doing some cropping to make it perfect. Having 15 MP to play with can be a life savior here. Of course, if I only did portraits where I have time to pose my subjects this would be less important to me.

There is a small difference in the resolution of the images from the 15.1 MP Canon 50D and the 12.1MP Nikon D300.

C. High ISO Performance

The ISO setting control how sensitive the image sensor is to light. As the light gets lower you can increase the ISO to avoid using the flash. This is really important when you want to shoot in available natural light such as at dusk or at dawn when the light is really beautiful. Another example is when you want to photograph a bride and groom during the first dance without using the flash so you capture all the romance. The downside to increasing the ISO is that the resulting photos will tend to get grainier as the ISO increase.

The Canon 40D allowed me to go to ISO 1600 and then expand it to ISO 3200. When I just started out doing casual shots this was okay. However, I find that I often needed to go higher than 1600 and of course I was forced to use ISO 3200. On the Nikon D300 I could go all the way up to ISO 3200 standard so if I needed to use anything higher than ISO 1600 I would use the Nikon D300. That way if I only needed ISO 2000 I could use that setting rather than use ISO 3200. I must let you know that Nikon did fix the high ISO performance issues that plagued its DSLRs prior to the Nikon D300.

The Canon 50D now comes with a standard range of ISO 100 to 3200 just like the Nikon D300. However, the concern that I had was that with the big increase in MP count there would be much more noise (grain) at the higher ISOs. The more MP you have the more noise you tend to get at higher ISOs. I would have much preferred a smaller MP count and better high ISO performance. However, the engineers at Canon have really outdone themselves this time. The high ISO performance of the Canon 50D is just as good as the Nikon D300 even though it has 3MP more. Much of this is due to the fact that Canon is now using gapless micro lenses on the image sensor. This seemed to have really increased the light gathering capabilities of the pixels.

The Canon 50D ISO can be expanded to 6400 (H1) and 12800 (H2). The Nikon D300 can only be expanded up to 6400. However, on the Nikon D300 you can go from 3200 to H0.3 and then to H0.7 before you get to H1.0 which is 6400. This is more flexible than having to go straight to 6400 since you should generally try to use lower ISO speeds.

You might be thinking that it is absurd that anyone should want to use ISO 6400 and worse ISO 12800. However, there are times when getting the shot is more important than the quality of the shot itself. A good example here is when shooting sports. If the light becomes very bad for whatever reason you will need to increase your ISO as much as possible to get high enough shutter speeds to freeze the action.

D. Auto ISO Range (100 to 1600)

I have been to Butterfly World on several occasions to get photos of butterflies, birds and the tropical plants there. It is normally very sunny so to save time I shoot in Aperture priority mode. This allows me to simply set the aperture and then let the camera automatically set the shutter speed based on the current ISO and aperture settings. One thing about South Florida is that one minute it can be very sunny and then in just a few minutes it can become real cloudy. The problem this pose is that when it becomes real cloudy the shutter speed selected by the camera can be so low that it would result in camera shake which in turn results in blurry images. When I just started out my photography this actually happened to me as I would simply forget to check the shutter speed that was selected by the camera.

The auto ISO feature lets the camera automatically change the ISO to suit the shooting mode. For example, when in aperture priority mode if the camera detects that the shutter speed selected would result in camera shake it automatically increases the ISO. This feature is available on the Canon 40D. However, the maximum ISO it would automatically set is 800. The Canon 50D will now set ISO up to 1600 which is a lot more flexible.

The Nikon D300 actually takes the auto ISO concept further by allowing you to set the maximum ISO you want the camera to set and the minimum shutter speed you are willing to work with before the camera start to automatically set the ISO. This gives ultimate control to the photographer.

E. Burst Buffer

Another concern I had with the big increase in MP count was the impact it would have on the burst rate. With the MP count going from 10 to 15 this would normally result in a much slower burst rate. However, the new DIGIC IV image processor is a lot faster than the previous DIGIC III processor so the burst rate is pretty much the same at 6.3 frames per second from 6.5 frames per second. If you use a UDMA card with the Canon 50D you can buffer up to close to 90 large/fine JPEGs versus the 75 on the Canon 40D. The Nikon D300 can store up to 100 large/normal JPEGs at a burst rate of 6 frames per second. With the optional MB-D10 batter pack you can get 8 frames per second.

F. Lens Peripheral Illumination Correction

It is just a fact of life that the light entering a lens tends to fall off around the edges. This tends to be more pronounced when the lens is wide open. The resulting photo will appear dark around the edges. You will see it sometimes referred to as Vignetting. It is more common on cheaper lenses. However, even the most venerable and expensive lenses are not immune to this problem. I have sometimes seen it on my professional grade lenses such as the Canon 100-400mm f/4.5-5.6 L IS lens and even the Nikon 70-200mm f/2.8 G lens.

If you have Photoshop CS3 you can quickly correct this problem. However, that is still one more thing that you have to worry about which increases your workflow. Read more ›

Canon G12 10 MP Digital Camera with 5x Optical Image Stabilized Zoom and 2.8 Inch Vari-Angle LCD

So I owned a G11 - and for whatever reason sold it a few months back. I have since tried the Panasonic Lumix DMC-GF1, Panasonic Lumix DMC-LX5 and Samsung TL500. This whole time I was searching for something better than the G-series - I only found it with the GF1 - but it is too large to be a compact.

I only give this camera 4 stars instead of 5 for the following reasons.

1. External Speedlite control - you still need a "Master" unit like a 580EX II or Canon STE2 to control external Speedlites. Canon should get off their butt in this area to compete with the new Nikon P7000. I almost considered going the Nikon route just to have that feature built in. Canon - start paying attention to what David Hobby says.

2. The screen is only 460K resolution. The Nikon mentioned above is 960K. The Samsung TL500 I mentioned above sports a beautiful AMOLED screen that knocks this one out of the park.

3. The pathetic optical viewfinder. You are catering to those people that say a camera MUST have one of these - stop it. You are wasting space with something so awful that even a disposable camera does better. I would rather have a higher resolution bigger screen (or a smaller camera) than this awful piece of warped tunnel-vision.

4. The rear control wheel is too small - enlarge it so it feels more like one of your DSLRs.

5. While the lens is gorgeously sharp (I mean competing with some of my L-lenses sharp) - f/2.8 to f/4.5 is slow.

6. The lens needs to be wider - 24mm f/2 (or even f/1.8 in the Samsung) equiv is the primary reason I tried the LX5 and TL500 before going back to Canon.

7. No microphone input for video recording.

8. Just too big and bulky - slim it down (but do NOT remove the articulating display).

So 8 knocks like that might sound like a big deal - but believe me when I say this - the camera is phenomenal.

Image quality is outstanding - I have had to process my RAW files with their converter (typically use Adobe Photoshop Lightroom 3 - but even with their converter image quality is second to none in the compact world. I actually prefer to do product shots with a G-Series than my usual 5D2 kit due to the flexibility and increased depth of field. The lens is magnificently sharp. HD video results look pretty good - but not stellar. It'll do in a pinch - but its no camcorder replacement.

Operation speed is very very good. I have read a few posts saying that focusing speed is vastly improved from the G11 - I haven't found that to be the case but none-the-less its pretty good.

Construction quality is pretty good - but I don't like the rough textured finish as much as the smooth finish on the G11 - it somehow makes it feel cheaper.

Controls are absolutely second to none. Dedicated EV and ISO dials are wonderful. The new front control dial is great. The rear dial however could use a bit of an extension - hard to operate quickly with my fat thumb. The whole camera is a little fat - slim it down and kill the awful optical viewfinder. Would like a dedicated movie button like pretty much all of its competitors. The articulating display is fantastic - PLEASE include this whenever you update the 5D.

Value for the money is mostly good - but if you are like me and need on-camera control of external flashes add a whopping $200+ for the ST-E2.

All in all a fantastic camera - even if it is a minimal update to the G11.

Why I picked it over LX5 > See my LX5 review - but I didn't particularly like that camera. Biggest reason would the articulating display followed by the awful screen resolution when composing on the LX5.

Why I picked it over the TL500 > I couldn't get the TL500 to trigger external strobes using radio triggers - that plus the lens is MUCH sharper on the Canon. I must have a bad copy of the TL500 as finding a sharp photo in my 50+ test shots is pretty hard.

Why I picked it over the S95 > Hotshoe and articulating display. If the S95 had those it would win hands down.

Why I picked it over the P7000 > Articulating display is about it here if you don't take into account I already own several Canon Speedlites.

Why I picked it over the GF1 or EP1 > Size + Nikon P7000 comments.

Hope you found my review helpful - if so please click the link below!

Edit 30 days in: I would add one more negative - once you lock focus in video to start recording - that focus cannot be changed after the fact - disappointed in that.

Also - I dropped mine this morning =( from 4ft onto concrete. Surprised that everything still works great and as expected it got marred up and one corner's metal is a little bent - but it still works which is impressive.

Canon Digital Rebel XTi 10.1MP Digital SLR Camera

[This is the same review I posted for the kit. If you're getting the body because you don't like the 18-55 lens, keep in mind that some dealers offer this camera in a kit with the much nicer 17-85 USM IS (image stabalization) zoom.]

The new Digital Rebel XTi camera should appeal to a wide variety of users: those wishing to upgrade from a point & shoot digital, or those wishing to improve upon their first generation digital SLRs. Features and value make this a 5-star camera, but it won't be everyone's cup of tea.

Compared to the previous Digital Rebel XT, important improvements are:

1) 10.1 megapixels. In digital camera circles, this is like saying a car has more horsepower than an older car. While this alone doesn't mean "better" pictures, in reality, combined with other improvements in hardware & software, the results typically are better.;

2) 2.5" LCD panel. This alone has more than one advantage. The obvious first one is that our pictures look larger in review. The second, and for someone approaching 50 (like myself), is that the LCD is now used for all the camera's data (shutter speed, aperture, shots left, etc.). It's much easier to read than the small LCD typically located on the top of the cameras. It might use up the batteries quicker, but, heck, if you can see the info this much easier, then so be it. One complaint, it does not appear that the data rotates when you do verticals (like the Sony Alpha 100).;

3) 9-point AF. The number of points are improved from 7, but the real key here is that it's the system from the 30D, which had a much higher degree of accuracy than the previous Rebels.;

4) Picture Styles. I didn't really appreciate them at first, but simply put, this is like the days of film, when we could use a "portrait" film or "landscape" film. For those that don't like to do a lot of computer work, these can be VERY handy in getting the right look in the camera.;

5) Dust cleaning system. OK, I think the dust problem will probably be a little overblown, now that Canon offers a solution, but it is a real, if not great, threat. Additionally, the way Canon has implemented it is second to none. The first is through hardware. An ultrasonic filter can simply shake the dust off. Second is through software. If you spot a nasty piece that won't shake off, you can do a reference shot, and have the dust removed by software on your computer.;

6)The grip has been improved a little. The rubber on the grip is improved, and an anti-slip strip has been placed on the back where the right thumb goes.

Most all other things Canon is know for still exists. The camera focus fast and quietly. Camera operations are quick and easy to locate and use. Pictures look great.

Now for the other side. This is an unusual time in that all the big players are comming out with a 10 megapixel camera at the same time, so the Canon has some stiff competition. Here goes a simple comparison.

1) Compared to the other two cameras already available, the Sony A100 and Nikon D80 (both also 5-star cameras), the XTi is considerably smaller, and somewhat lighter. Some will like this, even some with medium to medium-large hands. But most people with larger, and some with somewhat smaller hands may prefer the other two choices.;

2) The battery is somewhat smaller than its rival's, and may drain a bit faster due to the LCD being used for info all the time.;

3) Functionally, the rear LCD is not as nice as the Sony's. The Sony's rotates, can be set to enlarged type (50+ user again), and the system that turns it off as your eye approaches also starts the AF on the Sony. [Although many like the top LCD, the Nikon way of needing to push a button on the back, then peak over the top to see what you're setting is not as nice].;

4) No in camera stabalization. The A100 can shift the sensor to help eliminate camera shake. Nikon and Canon require you to purchase rather expensive lenses to get the anti-shake.;

Also, soon to be added to the competion will be the Pentax K10D. Specs are sketchy right now, but it appears to be enter the competition as a 10 megapixel camera with built-in anti-shake (much like their K100D).

Of these 3 currently on the market, the Canon is the least expensive; therefore, it's up to the other 2 to show they are worth more, a very difficult task, indeed.

Nikon D5100 16.2MP CMOS Digital SLR Camera

As a long-time owner of the Nikon D5000, and former owner of the Nikon D60, I was eager to purchase the D5100 after seeing the announcements and pre-reviews. Being one of the lucky ones to buy the D5100 with 18-55VR kit earlier this week, I've had a few days to play with this camera and can honestly say it's a solid upgrade to the D5000 I'm replacing, and should be on the short list of consideration for any "prosumer" looking to purchase a D-SLR with outstanding image quality, performance, and low-light capability in a lightweight, compact (for an SLR) body. And, unlike the D5000, this D-SLR finally has a usable Live View and HD video capabilities both with continuous autofocus.

First of all, it's important to understand where the D5100 fits in Nikon's capabilities. It is considered a "high-end enthusiast" D-SLR which means that it shares the same image sensor as the high-end D7000 without some of the higher-end features. If you're like me, very few of the D7000's features justify its extra cost and weight. The D5100 offers nearly the same image quality as its bigger brother in a less-expensive, smaller package, while adding a few tricks the D7000 doesn't have including an articulating display that helps you frame hard-to-reach spots.

Compared to its lesser-priced but still excellent brother the D3100, the D5100 offers improved image quality, speed, and resolution, along with a higher-resolution articulating display. For me, this is the sweet spot in Nikon's consumer D-SLR offerings.

The 18-55VR (3x) f3.5-f5.6 kit lens provides surprisingly good performance and image quality, although you'll likely outgrow it quickly. I have uploaded a few sample images taken with the D5100 and 18-55VR to show its performance and surprisingly good bokeh (pattern of blurred background) in large-aperture and macro shots.

For lens upgrades that include an AF-S autofocus motor, if you don't mind changing lenses, the Nikon 55-200VR is an outstanding value with excellent image quality, or consider the Nikon 18-105VR (5.8x) lens included with the D7000. If you don't mind some distortion and image softness, the 18-200 VRII (18x) lens may be your perfect "walkabout" lens. For me, I bought the pricey but outstanding Nikon 16-85mm VRII. Don't forget the Nikon AF-S 35mm f1.8 (if you can find it).

Low-light performance is outstanding with this camera, and the level of detail captured by the D5100 is excellent, even at higher ISOs. You're best capturing in RAW or RAW+JPEG mode (three different JPEG compression levels are offered) if you need to go back and fine-tune exposure or other settings after the shot. Nikon also offers "Active D-Lighting" which is a highly effective method for improving dynamic range of a photo to equalize the difference between high and low-light areas of a photo.

Interestingly, the improvement in image quality compared to my D5000 isn't dramatic. Given the incredible improvement I saw when upgrading from my Nikon D60 to the D5000 perhaps I had unrealistic expectations for this new sensor. But in most image settings, even low light, the improvement is noticeable but subtle. That speaks more for the outstanding quality and low-light sensitivity of the D5000 sensor (which is shared with the D90) than it speaks against the D5100. With the D5100 you get higher resolution for improved cropping, and the 14-bit RAW images offer greater dynamic range for more flexibility after the shot is taken.

Speaking of RAW format, as with any new camera, there is a bit of a wait until updates are available for your favorite camera software. As of May 18th, Adobe, Apple, and Nikon have added support for the D5100 RAW files, so you can use Aperture, iPhoto, Nikon View NX2 (v2.1.1 and later), Nikon Capture NX2 (v2.2.7 and later), Lightroom 3 or Photoshop CS5 (via Adobe Camera RAW 6.4 or later). If you use other photo software or another platform, you may want to verify RAW support for the D5100.

Compared to my D5000, Nikon has gone back and addressed most of my concerns on ergonomics and performance:

- camera body is roughly 10% smaller and 10% lighter

- 16.2 megapixel CMOS DX-format image sensor (shared with D7000) captures 14-bit RAW images and offers +1fs greater low-light sensitivity

- ISO 100-6400 range with expansion to 25,600 ISO (D5000 minimum is 200 and expansion to 12,300)

- high resolution (920k pixel) display for greater detail in image previews (although I had to bump up the default brightness one notch for accuracy)

- side-mounted articulating display no longer interferes with tripod (the D5000 display is inconveniently hinged at the bottom)

- dramatically improved (now usable!) LiveView mode with continuous autofocus even in HD video mode (more on that later)

- full HD 1080p movie capture without the "jelly effect" (unless you move VERY quickly from side-to-side), in more standard H.264 mode up to 22 min (D5000 is AVI format 720p up to 5min)

- slightly better control position (LiveView is now a rocker switch on the mode dial, Video Record is just behind and to the left of the shutter release)

- significantly quieter shutter release (plus, a "Quiet Mode" is available although hardly necessary)

- faster performance (4 frames per second)

- SDXC compliant supports higher capacity cards

- remote control sensor on rear now in addition to front-mounted sensor

- improved battery life, and an improved battery release

- battery charger now has built-in collapsable plug instead of requiring separate power cord

- MUCH better eyecap design no longer comes off in my small Nikon camera bag; also an improved diopter (eyeglass) control

- additional in-camera editing capabilities, including ability to trim video

- new "gimmick" special effects: in-camera HDR, selective color, night vision, etc

Let's start with the display - moving the hinge to the side not only makes the articulating display usable with a tripod, it makes the camera body shorter, so that it matches the height of most popular Nikon DX-format lenses and no longer leans forward when set down on a table as the D5000 did. It makes a surprising improvement in shooting comfort also. Nikon has improved the rubberized grip of the body and the thumb rest in the rear, although some have said that the grip is a bit shallow for larger hands. For my average-sized hands it is very comfortable.

The improved control placement is mostly welcome as well. LiveView is now a spring-release rocker on the side of the Mode Dial (VERY handy) and the video record button is also now on the top of the body, in front of the mode dial and behind the shutter release. What I didn't care for is the placement of the rear camera buttons, which now all shift above and to the right of the display to accommodate the left-mount hinge. What I don't like is that the "i" button (used to display and change shooting info) is too far away from the 4-way mode switch, so changing default shooting settings is a bit more of a stretch on my thumb. On playback, the delete button is just to the right of the Zoom buttons, instead of being far away like it should be. I didn't find myself accidentally deleting photos, but I'd rather have had a button closer by that I use more frequently (like the Menu button?) With these two buttons near each other, I always found myself accidentally hitting the "I" button instead of RECORD to capture video. So watch your screen and make sure you actually are recording when you think you are!

What has dramatically improved from the D5000 is LiveView performance and HD video capture. Neither are perfect, but compared to my D5000 both are quite usable in the D5100. In LiveView mode, the D5100 tracks faces and subjects quickly and accurately, although still nowhere near fast enough for sports events or that "quick shot" like you might be used to with a compact camera. On my D5100, LiveView autofocus typically took half a second in lower-light conditions, which is no match for the viewfinder, but a huge improvement from the D5000.

Video capture is another notable improvement in the D5100, capturing single videos up to 22 minutes of 1080p HD (if you have the SD card capacity), in H.264 format, with continuous autofocus. Nearly gone is the "jelly effect" of the D5000 when you panned horizontally and the video appeared to bend. Compared to video captured on the D5000 which almost always exhibited this "jelly effect", I have seen none of these artifacts except in the most extreme fast horizontal pans. In theory, the continuous autofocus sounds like a great improvement for video capture, but in practice I found it slow to react (especially in low-light situations). Too often I found the camera "searching" for the correct focus, even with the (optional) Nikon 35mm F1.8 AF-S lens. It was so distracting that I ended up disabling autofocus and learning how to manually adjust focus as I moved from subject to subject. Also disappointing is that like the D5000, the built-in microphone is monoral. For stereo sound, I highly recommend the Nikon ME-1 external microphone (which doesn't require batteries and mounts in the hot shoe). Overall, the video capabilities are promising, especially at 1080p, but I am more satisfied with the native 720pHD stereo video captured from my Canon S95.

Rounding out the list of improvements and new features of the D5100 are the new "special effects", including the first in-camera HDR mode for any Nikon D-SLR. In practice, while there may be edge cases for these effects, I am not particularly impressed with any of them, including HDR. First of all, you cannot capture RAW with any of the effects. For HDR, there are further limitations (can only be used in P-S-A-M modes, not auto, no flash, etc). Read more ›

Canon EOS 60D 18 MP CMOS Digital SLR Camera with 3.0-Inch LCD (Body Only)

The purchase process was normal and the delivery was fast and they kept me informed about my item all the time.

This camera is wonderful! Works as a charm and has many, many options that can be very useful at all times. Im an semi pro photographer and this camera is excellent for me, heavy work most of the time. Its fast, easy to use, responds great to all the commands. The menu screen is very easy to use.

Image quality is excellent, very crisp, clear and brilliant, even at very high ISO (1600 and above). Anyway, you must keep in mind that as important as the camera, the lens you choose is. With this very same camera but a crappy lens the images could be disappointing, so try to get a good lens before you cant talk about the camera.

The swivel screen was a key point when I made my choice and it's a wonderful feature once you try to take pictures in awkward positions.

Battery life is better than I expected.

I dont regret at all to had choose this one over the 7D. Same resolution, same video capacity and it has the plus of the swivel screen for less money.

I recommend this camera a lot, but be sure to get good lenses (this goes for all cameras as well)

The XT is amazing. The battery comes partly charged so you can immedietly start using the camera (thank you Canon!) I've already shot about 200 pictures with it and the battery hasn't died yet.

I can't give you a comparison between the XT and the 20D as I haven't owned a 20D, I can tell you a few things you may wish to know before buying.

This camera, is TINY. Extremely tiny. I'm a woman in my early twenties and I have small hands. The camera fits just right in my hands, but honestly, I don't see how someone with bigger hands would be 100% comfortable holding this. If my hands were any larger, they would be slipping off the bottom.

I had tried holding a 20D at a camera shop once and it felt too large in my hands to grip. The camera size is perfect for me, but just beware if you have larger hands. You may want to look into the battery grip, or test out holding the camera at a store before you order it. See the picture I uploaded above to get a size relation and how the camera fits in my hands.

For anyone who is migrating to this camera from a standard point and shoot digital camera, you cannot frame the image you are about to take using the LCD screen on the back. You must look through the viewfinder. The LCD screen is soley for menu use and preview mode after the picture has been taken, nothing more.

Something I've noticed is the camera makes a ratteling sound when moved around. I couldn't figure out what the heck it was, and then I finally reazlized it's the hinges from the pop-up flash. It sounds like they are loose when the flash is closed. I went to Best Buy and looked at their display model, and yep, it has the same problem. Well, it's not really a *problem* but frankly something ratteling around like that sounds cheaply made to me. My Canon film SLR doesn't make that sound.

I use a 420EX Speedlite flash with my SLRs so the popup flash doesn't concern me, but it was something I noticed and thought I would share.

I love that Canon gave the option to have a black finish over a silver one.

The startup time is instantaneous which is absolutely wonderful.

The burst mode is excellent with 3 fps.

It's extremely quiet.

The image quality is excellent. You can get photo quality prints at 20x30, and even then I bet you could push it further.

I really can't elaborate more then what other reviews have said. If you are looking for a step into the digital SLR world, this is the ticket. Or you can even check out the newly reduced original Digital Rebel, but for the extra hundred bucks or so, I would just get the XT. You will not be sorry.

Two upgrades I would make right away: Get a Speedlite flash and the Canon 28-135mm lens.

Also, I don't know why people are submitting bad reviews grading Amazon on shipping for the Rebel XT. When I preordered the XT from Amazon (not from another 3rd party), it said it would be released March 20th. I got my Rebel XT in the mail yesterday (the 22nd) which if you ask me, is pretty darn good. Want something right away? Then walk into a store and buy it instead of ordering from the internet.

Canon Digital Rebel XTi 10.1MP Digital SLR Camera

[This is the same review I posted for the kit. If you're getting the body because you don't like the 18-55 lens, keep in mind that some dealers offer this camera in a kit with the much nicer 17-85 USM IS (image stabalization) zoom.]

The new Digital Rebel XTi camera should appeal to a wide variety of users: those wishing to upgrade from a point & shoot digital, or those wishing to improve upon their first generation digital SLRs. Features and value make this a 5-star camera, but it won't be everyone's cup of tea.

Compared to the previous Digital Rebel XT, important improvements are:

1) 10.1 megapixels. In digital camera circles, this is like saying a car has more horsepower than an older car. While this alone doesn't mean "better" pictures, in reality, combined with other improvements in hardware & software, the results typically are better.;

2) 2.5" LCD panel. This alone has more than one advantage. The obvious first one is that our pictures look larger in review. The second, and for someone approaching 50 (like myself), is that the LCD is now used for all the camera's data (shutter speed, aperture, shots left, etc.). It's much easier to read than the small LCD typically located on the top of the cameras. It might use up the batteries quicker, but, heck, if you can see the info this much easier, then so be it. One complaint, it does not appear that the data rotates when you do verticals (like the Sony Alpha 100).;

3) 9-point AF. The number of points are improved from 7, but the real key here is that it's the system from the 30D, which had a much higher degree of accuracy than the previous Rebels.;

4) Picture Styles. I didn't really appreciate them at first, but simply put, this is like the days of film, when we could use a "portrait" film or "landscape" film. For those that don't like to do a lot of computer work, these can be VERY handy in getting the right look in the camera.;

5) Dust cleaning system. OK, I think the dust problem will probably be a little overblown, now that Canon offers a solution, but it is a real, if not great, threat. Additionally, the way Canon has implemented it is second to none. The first is through hardware. An ultrasonic filter can simply shake the dust off. Second is through software. If you spot a nasty piece that won't shake off, you can do a reference shot, and have the dust removed by software on your computer.;

6)The grip has been improved a little. The rubber on the grip is improved, and an anti-slip strip has been placed on the back where the right thumb goes.

Most all other things Canon is know for still exists. The camera focus fast and quietly. Camera operations are quick and easy to locate and use. Pictures look great.

Now for the other side. This is an unusual time in that all the big players are comming out with a 10 megapixel camera at the same time, so the Canon has some stiff competition. Here goes a simple comparison.

1) Compared to the other two cameras already available, the Sony A100 and Nikon D80 (both also 5-star cameras), the XTi is considerably smaller, and somewhat lighter. Some will like this, even some with medium to medium-large hands. But most people with larger, and some with somewhat smaller hands may prefer the other two choices.;

2) The battery is somewhat smaller than its rival's, and may drain a bit faster due to the LCD being used for info all the time.;

3) Functionally, the rear LCD is not as nice as the Sony's. The Sony's rotates, can be set to enlarged type (50+ user again), and the system that turns it off as your eye approaches also starts the AF on the Sony. [Although many like the top LCD, the Nikon way of needing to push a button on the back, then peak over the top to see what you're setting is not as nice].;

4) No in camera stabalization. The A100 can shift the sensor to help eliminate camera shake. Nikon and Canon require you to purchase rather expensive lenses to get the anti-shake.;

Also, soon to be added to the competion will be the Pentax K10D. Specs are sketchy right now, but it appears to be enter the competition as a 10 megapixel camera with built-in anti-shake (much like their K100D).

Of these 3 currently on the market, the Canon is the least expensive; therefore, it's up to the other 2 to show they are worth more, a very difficult task, indeed.

More Review : http://canonslr.babybi.com

There are plenty of good reviews on this, so I'm not going to get into too much detail other than to say it is WELL worth a couple hundred bucks. (and then some) I bought it, took some test shots and blew myself away. It's surprisingly sharp, even wide open! Now, if you step down a couple and pull back on the zoom it just gets better. around 2 steps down at 200mm seems to be a sweet zone for this lens (at least in the quick testing I did). IS is very effective, and the bokeh looks great. I had a seasoned shooter who lives w/ the 70-200L f/2.8 take a look at the test shots, he was impressed as well. So, its not just me.

I do have a couple complaints.... A: It is slower... focusing full range takes some time. B: It is slower... only f/4.0 at best, so you will be shooting higher iso, longer shutters etc in lower light. But, both of those are to be expected, so I will not hold those against the lens... just like inner focus would be better etc. It's a $200 lens, you cant expect $1500 lenses to not have anything on it...

Lastly, my biggest complaint is that it DIDN'T COME WITH MY CAMERA! Ok, not a complaint on the lens, but it's really an impressive lens for the cost and so far I love it. It's not an "L" lens, so don't expect to get the same results. But for $200, I would buy it again and again.

Canon EOS Digital Rebel T3i 18MP SLR Camera 18-55mm & 75-300mm Instant Rebate Bundle

I bought this bundle impressed with the value of the contents for the price. Boy was I wrong! I should've bought the camera on its own and the individual pieces locally at a camera accessory store. The T3i and 18-55mm lense are great! The 75-300mm lense is NOT the IS-USM(image stabilized, ultra sonic motor) version. It doesn't have the image stablization which is helpful for a lense with that range. Also the focusing is loud and slow compared to the USM version of the same lense. The extra battery included is an off brand and is super light. Compared to the Canon battery that comes with the camera I doubt this battery weighs 1/3 or performs for very long at all. The SDHC 16gb card that came with the bundle is only a class 2 (the lowest, new cards are class 10), which means transfer from the camera to the card is slow, extremely slowing down the rapid fire/burst function. The 'high speed' card reader is junk. The 1st time I used the reader to transfer images to my computer it corrupted the SD card and gave me a 'card access error.' I lost all my photos! I have since found out I could've taken the card to a local camera shop and they have a rescue program to restore corrupted cards (If I had only known before I accepted the loss of some great photos and formatted the card). The camera bag is decent quality. The tripod is super cheap and low quality. The neck on the tripod will not stay up (no locking feature) and is wobbly. First time using it with a light breeze outside and the tripod nearly blew over with my camera attached! Luckily I caught it.

All in all, I would NOT recommend this package even though I do recommend the camera. I have since had to purchase a new class 10 SDHC card, new HQ tripod, and new high speed card reader.

Canon EF 50mm f1.4 USM Standard & Medium Telephoto Lens for Canon SLR Cameras

With the 50mm f1.8 lens available for less than a hundred dollars, why spend so much more to get the f1.4? The answer is, you may not need to. It all depends on your seriousness, budget, and how long you need your lens to last.

If you want a "starter lens" for shooting at 50mm (or with prime lenses in general), the f1.8 would be a great buy. 50mm is a very useful and intuitive focal length to spend some time with, because it will portray the world through the viewfinder at about the same distance as your naked eye on all of Canon's consumer-priced dSLRs with the 1.6x crop factor*. (*Updated after extensive discussion in the comments.) So you could buy the f1.8 cheaply, regard it as a "play with it" lens, and get a nice introduction to "prime lens quality." The f1.8 will seem like a substantial step up from kit lenses and most consumer-priced zooms, and amazing bang for few bucks.

So if the f1.8 is such a great bargain, why would the f1.4 be among Canon's most all-time popular lenses? It's that the f1.8 can take the great shot within certain conditions, but the f1.4 delivers within a much wider range of conditions. In other words, "You get what you pay for," and we'll save the best for last.

Affordable-but-Solid Contruction: The f1.4 will likely have a much longer life than the cheaper plastic build of the f1.8, and retain more resale value. It's an investment, rather than a commodity. And it'll be more certain on your camera and in your hand. (My first one finally needed some calibration, after 80,000 shots and extreme wear-and-tear from frequent swapping with my other primes.) Users sometimes report the front glass falling out of their f1.8s. For the f1.4, the main issues revolve around the Micro USM focus motor, which is not as sturdy as true USM.

Focus Versatility: The f1.4 lets your camera autofocus, and then lets you tweak further by hand without flipping a switch - that's called "Full-Time Manual Focus." The f1.8 requires switching back and forth between auto and manual focus. The f1.8 is famously noisy/buzzy during autofocus, has a bare-minimum focus ring, and no distance scale. The f1.4 will autofocus more reliably, especially in dim light, though it will fail occasionally when starved.

Resistance to Abberation: Chromatic abberation (fringe colors) and barrel distortion are evident-but-low for both lenses at wide apertures - that's "prime lens quality." But in comparison tests, the f1.8 is more susceptible to vignetting (shadows around the corners), halation (glowing around the highlights), and lens flare. For instance, lens flare within the f1.4 tends to be more tightly controlled - "in focus" - whereas a bright light source is more like to blow out the whole shot in the f1.8. All these factors improve when stopped down, but lag about a stop behind the f1.4.

Color: However, if the f1.8 catches up at f/8 to the f1.4 by many standards, it rarely catches up to the f1.4's saturation. The f1.4 has "proper-to-strong" color richness at all but the widest apertures, while the f1.8's shots are much more likely to require postwork. (I do, however, get better saturation from my 24mm f2.8 and 100mm Macro f2.8. The 50 f1.4's saturation seems good-not-great by comparison.)

"Headroom": The engineering of both lenses lets you choose the tradeoff between "most possible light" or "most possible clarity." It's by design that you can choose "more light for less crisp," or stop down for sharpness. *Samples vary*, but the average 50mm f1.4 should consistently "get down to sharp" more quickly, "sharp enough" by f/2.0, "very very sharp" by f/2.8 (often exceeding the professional 24-70mm f2.8 L when wide open), and delivering "unreal sharp" by f/4. (I saw insane "specks of mascara sharpness" at f/3.5 from my first f1.4.) Again, the f1.8 will probably lag about a stop behind that curve.

My second 50mm f1.4 performed even better than my first, right out of the box, "marginally sharp" at f/1.4 and increasingly beyond reproach by f/1.8-2. (At f/1.4-1.6, it suffers only from halation and some light fall-off in darker areas.) So if extreme sharpness is necessary for you, shop with a strategy that will let you return your lens or get it calibrated if not up to your needs. My guess is that my first one was more typical out of the box, but it approached the performance of the second after calibration.

(It's also worth noting that the premium-priced 50mm f1.2L is drastically more sharp (and better performing generally) at wide apertures, but *less* sharp at f/2.8 through f/8. The f1.4 is a better "walkaround" performer than the f1.2L lens that costs four times as much.)

Regarding light return specifically, my own experience in lens-swapping baffled me, until I read other reports that the f1.4 exposes a third of a stop brighter than most other Canon lenses. It's brighter in the viewfinder generally, and really IS a whole stop "faster" than the f1.8 at maximum apertures (i.e., the same net exposure at half the shutter speed). If you're willing to sacrifice some clarity, that extra stop can make a huge difference when you're challenged by moving targets in low light.

(For instance, shooting "wide open" for performers in dim venues. Faster shutter for less motion blur. More light for better color. And the edges may be soft at 100% magnification, but *relatively* clear compared to the out-of-focus background. That "illusion of clarity" isn't as likely to print very well, but resizes very snappily for the web.)

So the f1.8 can certainly produce some stunning images, particularly in general daylight photography OR tightly-controlled conditions OR stopped down, but is less adaptable to challenging circumstances that the f1.4.

"The Best for Last...":

Now, with both these lenses, you get the advantage of marvelously wide aperture, which can be used for a tight focal plane that lets the background (or foreground distractions) fall quickly out of focus. This is of course a cornerstone of creative photography, and both lenses give you plenty to explore. (In practice, even f/2.8 delivers a pretty shallow depth of field in close-up shots, so these wider lenses give you even more room to play.)

However, there is such a thing as "blur quality," called "bokeh," based on the number of aperture blades within the lens. The f1.8 has five, and the f1.4 has eight. The f1.8 will portray out-of-focus lights more pentagonally, the f1.4 more roundly. (In focus, those same lights will be eight-pointed stars with the f1.4, ten-pointed with the f1.8 - odd numbers of blades double the number of points.) But most importantly, the blur from the f1.8 can be rather "choppy," especially at wide apertures, while the f1.4's is consistently more "buttery smooth."

In other words, there's more to quality than sharpness - there's also quality where your shot is LESS than sharp. And this is where the f1.4 becomes "a favorite lens" for some people, even at over three times the price of its diminuitive counterpart.

Make no mistake, the f1.8 would make an excellent "starter" lens. But the f1.4 is an exceptionally *serious* lens. Are you still learning to love photography? Then $80 is a fine price to pay for a lens you might outgrow. Or do you already love photography? Then $300 is a worthy price for a true investment that will reliably pay off. So they're both bargains, just buy what's best for you.

(Addendum - Canon also sells a 50mm f2.5 Macro lens around $250. If you NEED macro, it's reportedly pretty good, and for general purpose as well. But it's a) not even as fast as the f1.8, b) more difficult to manually focus than the f1.4, and c) not as creamy in the bokeh, with six aperture blades instead of eight. And Canon's 100mm version is drastically more practical for macro work, and better performing generally. But the 50mm Macro does become a contender, at a "middle price," if what you really need is one decent lens to do as many different things as possible, though none of them as well.)

For the cost of this camera, I don't think you can get anything better. The low light performance is off the charts. As a wedding photographer I regularly shoot with Nikon's high end professional equipment and I was amazed how close this camera is to a pro camera. Now let me get specific. In order to compare I took a look at 100% files out of each camera I own.

Which camera excels Nikon D3100($Cheap) VS. D300($1600) VS. D700 ($2,700):

* Lens = The D3100 is the only camera that comes with a lens at it's normal price

* ISO Performance = Tie between D3100 and D700! (It could be Nikon's new processing but the JPEG looks fantastic I was shooting D3100 on 6400iso with very little noise at all)

* Low Light Focusing = D700

* Focus Speed = D700

* External Buttons & Controls for Pros = D700

* Menu Navigation = D3100

* Ease of Use = D3100

* Megapixel = D3100 (14.2)

* Sensor size = D700 (Much more important than megapixels but I won't get into this)

* Can use older lenses with functionality = D700 & D300

* Video = D3100 of course! 1080P video looks amazing.

* Frame Rate = D300 at 6 photos a second

* Weight = D3100 (light as a feather)

* Ergonomics = D700 (big enough for all my finger)

Lens:

The lens is a kit lens, it will work outside but not so great in low light. The Vibration Reduction will help indoors but Vibration Reduction can't stop a child or pet in motion indoors. Consider buying a 35mm 1.8dx AFS for around $200 and you will be super happy with this camera.

Video:

I purchased the 3100 specifically to shoot video, so I put on Nikon's brand new 85mm 1.4g Nano lens and shot video with it. The lens costs more than double the camera but I wanted to see how the 1080P video looked. It has the look of a cinematic movie. After the 85mm, I put on Nikon's 50 1.2 manual focus lens and was able to take very cinematic video in manual mode. In order to make it brighter or darker you either need to use a really old lens like the 50mm 1.2 and hit the AE-L (auto exposure lock) and twist the aperture to change exposure. Or you can hit the AE-L button when you get the exposure you like. Its not a perfect system but it works well for me. Inside the menu options you can change the AE-L button to hold the setting until you reset which is helpful.

Jello Cam (What's not so great):

This camera still suffers from the "Jello Cam" look in video if it is not on a tripod and you are shaky. The video can look like jello if moved too quickly. Use a monopod or tripod when shooting to avoid this. I'm not sure if a faster video frame rate 60fps would help - but at 24 and 30 it can suffer badly.

Conclusion:

This is an amazing deal! Unless you make most of your income from photography or have a stockpile of old lenses (this camera can only autofocus with AFS lenses) then this camera is the must have camera of the year. If you have good composition skills and an eye for light you can take photos worthy of a magazine with this. Seriously, you won't regret buying this camera. When you do, do yourself a favor and buy an additional Nikon AFS lens that has a maximum aperture of 2.8, 1.8 or 1.4. These lenses will take better portraits and deal better in low light than the kit lens.

Canon EFS 55-250mm f/4.0-5.6 IS II Telephoto Zoom Lens for Canon Digital SLR Cameras

I had owned Canon Digital Rebel XSi 12.2 MP Digital SLR Camera with EF-S 18-55mm f/3.5-5.6 IS Lens (Black) for about a year and I have discovered that the standard lens that it came with was rather limited in terms of what sorts of shots I was able to take, especially when it came to taking pictures of distant object. I was not willing to spend too much money on any of the higher end professional or prosumer lenses. I needed something that would take decent photographs under the normal shooting condition, something comparable to the performance of the standard lens. I also wanted image stabilization, as I had come to appreciate how important it was for making low-blur shots. This Canon EF-S 55-250mm f/4.0-5.6 IS II telephoto zoom lens fit that description perfectly, and over the time I've owned iy it has met or exceeded all of my expectations.

The lens, as can be expected, shoots good high-zoom pictures, especially in broad daylight. The image stabilization greatly helps in lower light condition as it eliminates a lot of the blur. However, I have not had much success with using this lens at night, even with really long exposure while using a tripod and a remote control. In my experience I got the best result when using this lens for shooting (relatively) nearby objects at high zoom. This would give me a really large contrast and the pictures that I got that way are among some of the best I ever shot.

This is also a fairly heavy lens, especially if you are not used to interchangeable lenses, so you need to plan in advance if you are going to use at a particular shooting situation or not. I discovered that it just fits perfectly in my regular sized DSL camera bag. Also, if you are using more than one lens at the shooting session be very careful when exchanging the lenses. I recommend always trying to find a flat surface on which you can lay down any one lens at a time.

Whether you are interested in taking close-ups of distant objects or creating some interesting artistic effects, this is a perfect lens to invest into after you've gotten used to taking pictures with SLR cameras.

Canon EOS 5D Mark II 21.1MP Full Frame CMOS Digital SLR Camera

Canon 5D Mark II

Never Ever: Rent, borrow or use the Canon 5D Mark II, if you do, you will have to own it. It's that good!

Pros:

Crazy high ISO performance

Fantastic amazing image quality you have to see to believe!

Great menus, sharper, brighter, easier to read then 40D

Video, did someone say video? I love it! You will need a tripod!

Fantastic rear LCD that you can check actual photo sharpness

Super low light high ISO photographic tool with 25,600 ISO!!!

Feels great in your hands, the grip texture is easy to hold and is well balanced

Low 50 ISO allows photos at F/1.2 aperture out in bright sunlight for shallow DOF

Cons:

No Built in popup Flash

A little slower shooting then the 40D

Very demanding of lenses, high end L lenses are a must have

Huge files: you will need larger memory cards and a larger hard drive

Ultra large bright sharp viewfinder makes my 40D finder seem dim and tiny

Hum... I'm thinking..

Intro:

I have had my Canon 5D Mark II for a little over two weeks now. And I'm having a hard time putting it down.

I tried switching back to my Canon 40D and the very first thing you notice is how small, dim and fuzzy the viewfinder on the 40D is compared to the 5D Mark II. Especially if you are older you will really appreciate being able to easy see and read information in the viewfinder not to mention you can actually manually focus with it. It reminds me of my switch from the Canon Rebel XTi to the 40D. It's that big a difference.

The Images are huge and quite simply stunning. Plus I find that I can get away with very low noise all the way up to 3200 ISO on the 5D Mark II where the 40D was very noisy. In fact I would not hesitate to say the 5D Mark II photos has less noise at 9,600 ISO then the 40D does at 1600 ISO.

Lenses:

I have never had the pleasure of owning a Camera that is this demanding of the lens you use. It's like an instant lens test. I haven't seen much in-depth lens as used on 5D Mark II information on the other reviews and decided this would be good to be included in my review.

All of these lenses are brighter in the viewfinder and focus much better on my 5D Mark II then on my 40D.

So, with that said after several hundred photos I can give you a rundown of my most used, most favorite, best performing and least used lenses that I have used on the 5D Mark II and a few un-expected surprises along the way.

1. Canon 200mm F/2 IS L lens. This lens is my new master of resolving power. Even wide open at F/2 it is sharper then any other lens I have ever used. I could go on and on but here's a few highlights: Lightening fast auto focus, F/2 speed at 200mm, unbelievable perfect 10 Images, public attention hog, otherworldly image stabilization, great build quality, weather sealed, fantastic perfect buttery smooth Bokeh and what a lens case! If you crave attention and demand the absolute best there is the do what ever it takes to get this lens on your Canon 5D Mark II. If you do not like public attention you may want to skip to number 2 in this list as I have never been asked so many questions about a lens as this one. But it's all worth it as the clarity, sharpness, Bokeh and colors are: otherworldly, insane, impossible, rare, perfect, out of sight, crazy!!

2. Canon 85mm F/1.2 II L lens. Without a doubt at F/4 (after the Canon 200mm F/2 of course) this lens delivers the clearest sharpest and most resolving power onto any photograph you care to take with the Canon 5D Mark II. The clarity has to be seen to be believed. At F/1.2 the Depth of Field (DOF) is scary thin and the edges are super soft which is great for female portraiture. The super soft creamy dreamy Bokeh at F/1.2 is much smoother on the 5D Mark II over my 40D. But stop this lens down to F/1.8 and it gets scary sharp and clear. Step it down to F/4.0 and it's at its sharpest and the only lens I have that gives you 100% pixel peeping razor blade edge to edge top to bottom perfect clarity in every single area of the photo. For some reason this lens is even sharper on my 5D Mark II then my 40D or Rebel, don't know why but it is. Guess it's getting the full resolving power to the 21 megapixel sensor.

Looking at a photo on my iMac taken with a 5D Mark II with this lens stopped down to F/4 is like standing there looking through an open window at the actual scene! You feel like you could actually open up the computer screen like opening a window and climb in!!!

The 85mm F/1.2 is your low light monster on the 5D Mark II, I don't have to harp too much on what an F/1.2 aperture and an ISO 25,600 can do for you at night. Let's just say you can go out into what appears to be a dark night and do hand held photos.

Not all is perfect as it's: expensive, heavy, and hard to focus wide open, focus lock does not work and it eats camera batteries at twice the rate of my other lenses. Also it doesn't focus as close on the 5D Mark II as it did on my 40D so you can't get head filling close ups. This isn't really a problem, as with 21 Mega Pixels I can crop no problem. However, all this is forgiven when I get back to my iMac and view the results. This is the very first lens I will reach for when using the 5D Mark II and the one that's on it 90% of the time. If I could have just one lens for a Canon 5D Mark II this would be the one! [...]

2. Tie! Canon 135mm F/2 L. It's small light and stealthy and has fastest and best auto-focus of any lens I have ever owned (after the Canon 200mm F/2 IS L). It even focuses pretty close on the 5D Mark II. This lens is amazing, the Bokeh looks like sweet candy and it's sharper wide open then the Canon 85mm F/1.2 II L lens is wide open and stop it down to F/2.2 and it's as sharp as any lens I have. It's not a zoom so it's not as versatile but it's a great waist up portrait lens out in public and in larger studios. It's one of my most used lens at outdoor public events along with the 85mm F/1.2 II L (renaissance festivals etc.) where I'm photographing people. For some reason this lens is a little sharper on my Canon Rebel and 40D I guess because I'm using the center of the lens and it's sharper on these cropped sensor cameras.

3. Canon 100-400 F/4.5 - F/5.6 IS L lens. This is the second most used lens in my 5D Mark II arsenal. This lens was my biggest surprise of the group. Its Ok wide open but it's a monster of clarity at F/7.1 like it never was on my Canon 40D. It also becomes useable on the 5D Mark II in wider shot situations where on the 40D it was only usable as a longer lens. Sporting the longest zoom range of any Canon zoom this lens has to be without doubt the finest Zoo lens ever made, [...] You can frame almost any animal in almost any exhibit perfectly. This is also my lens of choice for taking photos of people at events with the 5D Mark II and is the King of versatility on a full-framed sensor camera. This is my sharpest and clearest zoom lens by a long shot (no pun intended. It's as close to the you are there feeling of the 85mm F/1.2 lI lens as any zoom lens I have. It's only drawbacks are it's a little heavy, is slow aperture wise (that's Ok with the 5D Mark II high ISO capability) and it gets a huge amount of attention out in public. I don't care it's all worth it this is a must have lens with the 5D Mark II. Again, for some reason this lens is even sharper on my 5D Mark II then my 40D or Rebel, don't know why but it is.

5-26-2009 100-400 update: So I came back from the Riparian Bird Preserve yesterday where it was rather dusty and I noticed that my sensor and mirror box were full of dust. I decided to do a test on my 100-400 lens and sure enough it does pump dust into the camera body.

If you turn the zoom friction ring all the way loose and zoom in and out with the bottom end cap off there is no resistance. If you put the bottom end cap on tightly and zoom you can feel resistance. Then if you loosen the end cap just a little you can actually feel air being sucked in and out around the end cap as you zoom in and out.

Thank God for my FIrefly digital sensor cleaning system! And be forewarned if you own this lens.

4. Canon 17-40 F/4 L lens. This is my sleeper lens. A so so walk around lens on my 40D becomes a wide angle monster on my Canon 5D Mark II. This lens is soft wide open at F/4 but sharpens up noticeably at F/4.5 and becomes a super wide angle take it all in landscape and interior monster when stopped down to F/9 on a Canon 5D Mark II. This is a lens I always carry with me now since I never know when I might see a wide angle opportunity. Doesn't have the you are there feeling when viewing the photos on my iMac as much as the above three lenses but it's closer to perfection then you will ever see on a cropped sensor camera. I keep hoping that Canon will make a wide angle zoom that matches the performance of my Canon 100-400 IS L zoom lens. This lens has a similar sharpness on both the Canon 5D Mark II and cropped sensor cameras like my 40D.

5. Canon 70-200 F/2.8 L lens. This lens is actually about even with my Canon 100-400 IS L Lens in the zoom sharpness and clarity department but it's no where near as versatile on my 5D Mark II as the 100-400. Still it's a must have lens when shooting weddings when you need the super Bokeh background melting power of an F/2.8 aperture and lower light power of an F/2.8 aperture. The sharpness and clarity at F/2.8 that was Ok on the 40D is much improved for some strange reason on the 5D Mark II. And the Bokeh is much smoother creamier and richer on the 5D Mark II.

Just have to mention a great alternative lens the Canon 70-200 F/4 I/S L lens which I think is a sharper and better lens then the 70-200 F/2. Read more ›

Canon EOS Rebel T1i 15.1 MP CMOS Digital SLR Camera

I've had the T1i for about almost week now and after some extensive use, here are my thoughts:

1. 15.1 megapixel sensor. Yes, the high megapixel count is impressive, but keep in mind that, as you approach higher resolutions, you need to ensure the lens on the SLR can resolve that much detail. Sadly, the included 18-55mm IS lens is functional, but the high resolution really shows the so-so quality of the lens. Even if taken at the proper focus, pictures can appear soft with this kit lens. Shots I have taken with Canon EF-S 17-85mm and EF 70-200mm L lenses are crisp. I don't have any gripes on image quality. There are some issues with noise on the higher ISOs that don't seem to show up on the Nikon digitals, but overall, the quality is amazing for the price. Skin tones, textures, colors are reproduced very accurately.

2. Digic 4. The Digic 4 processor appears to process/save the 15 megapixel images in the same time (if not faster) than the Digic III processor on the XSi (even in RAW+Jpg mode). I have also noticed that at higher ISOs, the sensor and the Digic 4 produce images with less overall noise compared with its predecessors.

3. LCD. The 920,000 pixel LCD screen is large (3"), crisp, vibrant and fully visible even in bright sunlight. In comparison, the Canon XSi SLR (which the T1i replaces), also has a 3" LCD, but with 230,000 pixels. The viewing angle is great as well and the LCD can easily be seen nearly 180 degrees around.

4. ISO 12800. Canon and Amazon are correctly identifying that the T1i maxes out at ISO 3200. Some less reputable dealers are listing an ISO 12800, which you should disregard. The ISO 6400 and 12800 settings are expanded ISO settings. The pictures taken on these two settings are ISO 3200 images pushed to ISO 6400 or 12800 by the Digic 4 chip before saving to the memory card. These pictures are extremely grainy and contain a lot of noise to the point of only being usable as for snapshots or adding an artistic effect to certain compositions.

5. Penta-mirror. That Canon is still using one in the T1i is disappointing. The penta-mirror viewfinder image is functional, but still noticeably darker than that of the penta-prism viewfinder in the Nikon D90 (which is the T1i's main competitor). I really would have preferred if Canon had kept the XSi's 12.2 megapixel sensor, forgone 1080p video altogether, and maybe upped the cost of the camera slightly to cover the production cost of using a penta-prism in the T1i. Honestly, unless you are massively cropping your images, or creating large photos, the difference between 12.2 and 15.1 megapixels really is negligible.

6. Size. This is the same body as the XSi, and therefore a bit on the smaller side compared to other digital SLRs. I have small hands, so the T1i is comfortable for me. If you have big hands, I can see this being a very difficult camera to use over an extended period of time. If you haven't handled a Canon XT, XTi or XSi, I would suggest you go to a store and hold the T1i yourself before purchasing it online. (I will upload a picture of the T1i in my hands to the user gallery for a size reference.)

7. HD Video. Yes, the Canon marketing department made a horrible marketing decision and pushed the T1i onto shelves limiting the 1080p recording to 20fps (frames per second). Recognize this as a marketing gimmick that allows them put a 1080p sticker on the camera box. The 1080p @ 20fps is fine most times, but seems a choppy if you have a lot of action in the frame or are panning quickly. The T1i's 720p video is recorded at 30fps and is clean, smooth, and sufficient for all but the most discerning consumers. One major criticism though is that the sound is recorded in mono, AND there is NO input for an external microphone.

A lot of pre-production reviews of the T1i criticize its inability to automatically autofocus while recording. I wouldn't put much weight in this criticism, mostly because neither of the other two SLR cameras with HD recording capabilities (Canon 5D Mark II and Nikon D90) can automatically autofocus while recording either. What you can do with the T1i is pan/zoom the lens and then press the AE lock (*) button to make the camera autofocus on the new subject (all while recording). A problem with using the AE lock button to have the camera autofocus is that the microphone for the camera is on the front upper left of the body near the lens mount. Therefore, the lens motor noise is picked up just as much as ambient sounds. Even with my quietest Canon USM (ultasonic motor) lenses, this lens motor sound is pretty loud in video playback. Although, remember, you can always manually turn the focusing ring on the lens to get your subject back into focus. It's not easy, but after a little practice, it's not all too hard, either.

Ultimately, you shouldn't let the HD recording limitations sway you one way or the other. This is an SLR camera -- not a video camera. The HD video is a great feature, but if you're looking for something primarily to take video, look elsewhere. There are much better, cheaper VIDEO cameras out there which can record true 1080p.

8. Record button. For some reason, the record video button is next to the LCD screen (the same button used for direct printing). The first few times you take video, you'll intuitively find yourself using the shutter release button used to take pictures. The reason for this switch is that you can take a still picture while recording video, although, doing so will interrupt the recording.

9. Battery life. My first fully charged battery only lasted about 250 shots (no flash), but all charges since have given me in the range of 500-700 shots per charge. I'm guessing the first charge had such a short life because I spent quite a bit of time learning the camera, its menus, and settings.

10. Live View. I honestly can't review this as I haven't used it too much yet -- I prefer using the viewfinder. One feature I can say is nice is that, on the LCD, you can digitally zoom in (up to 10x) on a section of your shot to ensure it is properly focused. This, and the fine focusing, can really help if you're into macro-photography.

11. HDMI cable. The T1i has an HDMI Type C output on the body to allow you to directly display pictures and video on an HDTV. A minor criticism is that the HDMI Type C cable is not included in the box. You have to buy it separately. It would have been nice if it were included, as it's not an expensive cable.

Conclusion. The T1i is a bit on the light end, yet the construction still feels solid. For the camera's price point, you'd be hard pressed to find any digital SLR out there which gives you all the capabilities and growth range of the Canon T1i. The camera is intuitive enough for those new to photography to pick and learn easily, yet configurable enough for advanced amateurs. If video is not a big deal for you, then get the Canon XSi. There is very little the T1i has (other than ISO 3200 and a sharper screen) that the XSi doesn't. Plus, with the release of the T1i, you can probably pick up a used XSi for a great price on eBay. My wife recently gave birth, and I'm not looking to record endless (never to be watched) tapes of video footage of our son, but I do want several minute clips of him as he grows through the years. I've always been more inclined towards photography, so this camera gives me a very versatile digital SLR that I need with the wonderful capability of recording HD video that I want.

Canon EOS Rebel T3i 18 MP CMOS Digital SLR Camera and DIGIC 4 Imaging

The Canon Rebel T3i takes the consumer level dSLR a couple steps closer to the mid-level Canon 60D with the addition of the rotating rear LCD screen, remote flash firing, and in-camera processing features. The already highly competent, older Rebel T2i already shared many important features with the 60D (and even features of the semi-pro 7D) including the 18 MP sensor, 63-zone exposure metering system, high ISO performance, HD movie capabilities, and Digic 4 image processor. With these new upgrades, it might make it even more difficult to choose between them. But there are some important differences.

If you are considering the Rebel T3i vs T2i, the Rebel T3i is replacing the T2i. Since both cameras share the same 18 megapixel sensor and Digic 4 processor, both the T2i and T3i will create images with exactly the same image quality, produce the same low light/ high ISO performance, shoot at 3.7 frames per second, and have nearly the same size and build quality. They are both offered with the same 18-55mm kit lens (with some minor cosmetic differences on the new T3i kit lens). The T3i is very slightly larger and heavier due to the addition of the rotating rear LCD monitor. And that is one of the biggest differences between the two cameras. Do you want and need a vari-angle rear screen or not? The other major difference is the ability of the T3i to remotely control multiple off-camera flashes. Like the 60D and 7D, you can use the built-in flash of the T3i to trigger other Canon Speedlites. Some other minor additions to the T3i include the Scene Intelligent Auto Mode, which is a feature borrowed from point and shoot cameras. When in Auto mode, the T3i will make a determination of what type of scene you are shooting - close-up, portrait, landscape, etc. - and automatically configure the camera settings accordingly. However, if you want to use a powerful and costly digital SLR as a point and shoot, you should probably save the money and just buy a nice, high quality point and shoot like the Canon S95. Other additional but not essential upgrades include the in-camera processing Creative Filters, and the ability to choose different image size ratios and to rate your images. (Helpful hint: press the Q Button while in image playback and you can access features like rating, rotating, and Creative Filters.) There is also a marginally helpful Feature Guide which gives brief descriptions of various settings and some additional video features like Video Snapshot, which you can use to shoot short video clips that are automatically joined together into a video, with music.

Canon Rebel T3i vs. 60D vs. 7D

Sensor and Image Quality: All three cameras share a very similar sensor and 18 megapixels, and so their image quality will be virtually the same. All are capable of taking professional quality images.

Exposure Metering: The three cameras all share the latest 63-zone, dual-layer exposure metering system and 4 metering modes. That means they will all determine the exposure virtually identically and enable you to take properly exposed photos in most every situation, including difficult back-lit scenes. The size of the areas metered for Partial and Spot metering vary slightly between the cameras, but that isn't anything critical.

Autofocus: The T3i shares a similar autofocus system to the 60D, with 9 focus points and three auto focusing modes. However the 9 AF points of the 60D are more sensitive than those of the T3i: all are cross-type in the 60D, only the center is cross-type in the T3i. The 60D autofocus system is much less complex than the sophisticated AF system of the 7D with its 19 AF point system and its additional Zone, Spot, and Expansion focus modes. These various modes address how you want to deal with and group the numerous AF points. Plus the custom settings of the 7D allow one to customize how the AF system works - how it tracks subjects, how it deals with objects that come between you and your initial subject, how quickly it responds to these changes of possible subjects that are at different distances from you, etc. However, if you are not an avid sports photographer, a wildlife shooter, or someone who understands, needs, and will use the elaborate features of the 7D AF system, then this shouldn't sway you.

Construction: As you can probably figure out from the prices, each camera is not built the same. The T3i has relatively strong construction of a stainless steel frame with polycarbonate body. The 60D has a stronger and lighter aluminum frame and polycarbonate body, but not as strong as the 7D's magnesium alloy construction. The 60D also has some amount of weather sealing - more than the T3i, less than the 7D. But for most users, including even those using the camera daily or in travel situations, the construction of any of these cameras is far more than good enough, strong enough, and durable enough.

ISO: Since they all share a very similar sensor, the ISO sensitivity and performance at high ISO settings is virtually the same for these three cameras. But don't take my word for it, don't be swayed by pixel peepers on forums, instead check out the camera sensor tests at dxomark to verify this. As you can see, they all share the exact same overall score, and show very similar performance.

Controls: As with construction, the buttons and controls vary with these cameras. Unlike the T3i, the 60D and 7D have nearly every control an advanced photographer needs on the exterior of the camera and they also have the top LCD panel and rear Quick Control Dial that are not on the T3i. With all the cameras, any controls can also be easily accessed with the Q Button and Q Menu or in the other menus on the rear LCD monitor. The top buttons of the 60D set only one setting each, so this is less complicated than the multiple-setting buttons of the 7D. Canon has removed the white balance (WB) button on the 60D that the 7D has, but that isn't a big deal - use the Q Menu. Another change on the 60D is that the Multi-controller has been moved from the thumb joystick like the 7D and 50D and placed in the middle of the rear Quick-control dial. This doesn't change how it functions, and should just be a matter of getting used to the difference. If you plan on using your camera on Auto or Program most of the time, then the controls of the T3i are more than sufficient for your needs. If you work in Av, Tv, or M modes and need quicker and more direct access to your controls and the additional top LCD screen to view and change your current settings, then you need to consider the 60D or 7D over the T3i.

Menus and Custom Functions: These allow for greater control over customizing how the camera functions. The T3i has less Menu and Custom Function setting options than the 60D, and the 7D has yet a few more than the 60D. These settings enable you to customize the operation, function, and controls to work how you want them to, including things like exposure increments, peripheral illuminations correction for lenses (fixes dark corners), tweaking how the autofocus system operates, setting more precise white balance settings, and customizing which button does what. There are ebooks such as my Canon T3i Experience - The Still Photographer's Guide to Operation and Image Creation With the Canon Rebel T3i / EOS 600D and Your World 60D - The Photographer's Guide to Operation and Image Creation with the Canon 60D which walk you through all of the Menu settings and Custom Function settings so that you can set up your camera to work best for how you photograph, and also begin to learn to master all the advanced features, settings, and controls of these powerful dSLR camera.

Wireless Flash: Like the 7D and 60D, the T3i incorporates wireless flash triggering. This allows you to trigger multiple off camera flashes at different output levels. The T2i does not have this feature.

Articulating LCD Screen: The big new feature that the 60D and T3i have that the 7D and T2i do not is the articulating rear LCD screen. This may prove useful for videographers, as well as for setting up compositions while the camera is on a tripod, for macro use, or for using it from unusually low or high vantage points. Some users will be able to avoid buying an expensive angle finder because of this feature. There is also an electronic level in the 7D and 60D, visible in the viewfinder, rear LCD, or top LCD.

Viewfinder: The T3i has a pentamirror viewfinder with 95% coverage of the actual resulting image. The 60D has a large, bright pentaprism viewfinder with 96% coverage, not quite as nice as the nearly 100% view of the 7D pentaprism.

Processor: The T3i shares the same Digic 4 processor as the 60D. The 7D has dual Digic 4 processors. However, if you don't need to shoot dozens of continuous images, you probably won't notice any processing speed issues.

Continuous Shooting Speed: The T3i can shoot 3.7 frames per second. The 7D can shoot a blazing 8 frames per second, in which the photos barely change from frame to frame. The 60D can shoot a respectable 5.3 fps which is actually a more useful rate. If you need the extremely high fps for sports, wildlife, or other action shooting, get the 7D. If not, don't be swayed by this excessive feature.

Memory Card: The T3i and 60D use the SD memory card. The 7D uses the CF card.

Battery: The T3i and T2i use the smaller LP-E8 battery with less capacity than the LP-E6 battery used by the 60D and 7D.

Size and Weight: The T3i is smaller and lighter than the 60D, which in turn is smaller and lighter than the 7D. Read more ›
