With an ISO range of 100 up to 6400, a shutter speed of 30 sec down to 1/8000 of a sec, continuous shooting up to 5 frames/second, single or continuous bracketing and exposure compensating of -/+ 3 steps, this is the camera the up and coming professional will be seeking. When you consider the file size (up to 6048 x 4032) they added a second Bionz image processing engine to accommodate the huge data size.
The viewfinder of the A900 is both huge and very bright, and offers a huge amount of creative control as you would expect from a professional camera.

The A900 has two card slots, one for Sony’s proprietary Memory Stick Duo format, and it is possible to select which card your image will be stored.

* No Live View shooting capability
* In higher ISO settings in JPEG mode with the default noise reduction settings, the images are a little noisy over 800 ISO
* RAW mode uses 36 Mp/image

* There is absolutely no question that it can out-perform almost anything else on the market, outside of the larger studio type cameras. This camera is a high end professional camera without a doubt. DSLR-A900 is one of the highest-resolution digital SLR in the world, and also the first “full-frame” digital camera with an anti-shake function integrated into the body. Recommend using full-frame lenses with can be very expensive

Featuring a wide range of ISO settings, the 7D enables shooting from dawn through dusk. Because of the low-noise and high-sensitivity optimization, shooting in situations previously possible only with flash becomes as simple as a point and shoot camera.

Summary

This camera is in direct competition with Nikon and matches in all areas, especially with the photo quality and AF capabilities. When you consider that it takes 8 frames per second, you’re not going to miss any of the action. The video quality is very good and it handles extremely well with the intuitive button placement on the body and its hefty feel. This camera is no lightweight and itís not something you’re going to wear around your neck for a long period of time (without the battery, it weighs in at 1.8 lbs.).

This camera is by no means for the beginner, but rather meant for the advanced enthusiast or professional photographer.

Technical Specifications
* High Resolution 16.2 MP DX-format CMOS sensor
* High Speed 6 frames per second continuous shooting, up to 100 shots
* Breathtaking Full 1080p HD Movies with Full Time Autofocus
* Dynamic ISO range from 100 to 6400
* Ground-breaking 2,016-pixel RGB (3D Color Matrix) exposure sensor
* Magnesium alloy body covering front and rear making it (moisture and dust resistant)
* 2 memory slots for SDXC memory cards

Pro’s
* Excellent photo quality
* Built-in Speedlight flash with Intelligent Through The Lens Balanced Fill-Flash automatically balances the output of the Speedlight and the scene’s ambient light so you can light your subjects any way you like
* Two User Definable Settings (U1, U2) right on the Mode Selector Dial letting you store most camera settings so you can go back to them at anytime without the need for further adjustments or menu settings
* Dynamic ISO range from 100 to 6400 expandable to 25,600 (Hi2) lets you shoot in near darkness
* Compact EN-EL15 Battery lets you shoot over 850 shots, but up to 1,500 in many instances

Con’s
* The ISO control button is not ergonomically placed (you can’t feel where it is while you’re shooting)
* You can’t tell what ISO you’re shooting while looking through viewfinder unless you’re changing it
* Exposure bracketing shoots only maximum brackets 3 exposures.. (if you can’t capture the photo in 3 brackets, you’re probably not going to in 7 either)
* Autofocus accuracy is dependent upon the type of lens you’re using (the better the lens, better the focus) which is true in most high-end DSLR’s.

Summary:
If you’re looking for Nikon’s newest mid-range DSLR camera, you don’t have to look any further. This camera has all of the bells and whistles any photographer would want, be they professional or amateur camera enthusiast. The ISO range is fantastic, the battery life is great and it takes superb photos. A professional photographer friend of mine just purchased this camera for his wife so we know it’s exactly what you’d want as well. Of note though is this is probably not the best camera for the novice photographer.

The EOS 60D also features an EOS first: A Vari-angle 3.0-inch Clear View LCD monitor for easy low or high-angle viewing.

An improved viewfinder, a number of new in-camera creative options and filters, plus HDMI output for viewing images on an HDTV all make the EOS 60D invaluable for the amateur and up-and-coming professional photographer.

18.0-megapixel CMOS sensor and DIGIC 4 Imaging Processor; ISO 100-6400 (expandable up to 12800)
Includes 18-135mm f/3.5-5.6 IS UD standard zoom lens
Improved EOS Hi Def Video mode with manual exposure control
Vari-angle 3.0-inch Clear View LCD monitor

Note that the EOS 60 is not compatible with CF memory cards

Pro’s:
Excellent photo quality
Very fast auto-focus
ISO 100-6400 (expandable to 12800)
Built-in Wireless flash control
Great low light performance

Con’s:
Plastic body (feels much lighter but still very rugged)
Slow auto-focus in Live Mode
Auto Focus assist only works when flash is up, though flash can be forced off
White Balance is difficult to customize

Summary:

The camera has a great feel to it, takes wonderful photos and the battery life is super. With the tilt and swivel LCD screen, itís super easy to take videos as well as those ìover the headî shots. The Canon 60D is very fun to shoot with and takes great shots in low light. As I stated previously, this camera was just released by Canon in September, 2010 so you know youíre getting the latest and greatest from the manufacturer.

Summary:
A very good entry-level DSLR, this Nikon D3100 delivers excellent photo quality in a body that’s streamlined for experienced photographers, but relatively unintimidating for the less advanced photographer. If this will be your first DSLR, I would highly recommend this over the larger, heavier and more expensive DSLR’s out there. Its only weakness is performance; though solid, it nevertheless lags behind the competition in its lower frame-rate.

The D90 delivers the control passionate photographers demand, utilizing comprehensive exposure functions and the intelligence of 3D Color Matrix Metering.

Stunning results come to life on a 3-inch color LCD monitor, providing accurate image review, Live View composition and brilliant playback of the D90?s cinematic-quality 24-frames per second High Def D-Movie mode. Split-second shutter response and continuous shooting at up to 4.5 frames-per-second provide the power to capture fast action and precise moments perfectly. This is one serious camera for the serious photographer.

Some of the Technical Details for the camera include:
12.3-megapixel DX-format CMOS imaging sensor
ISO of 100 x 6400, when expanded
18-105mm f/3.5-5.6 AF-S VR DX Nikkon Zoom Lens
D-Movie Mode; Cinematic 24 frames per second HD, with sound
3-inch super-density 920 thousand dot color LCD monitor
Capture images to SD/SDHC memory cards

Some of the Pro’s are:
It has an Exceptional feature set for its price range on the market. When first introduced, this was the world’s first digital SLR capable of recording HD-resolution video. It was first introduced in 2008.

The New kit lens has good optical quality which is much better than average for kit lenses.
Of Note: For those of you that already have a Nikon, it will still drive old autofocus lenses as well as the new electronic lenses, something not included in the less-expensive Nikon D40, D40x, and D60 models

Some of the Cons are:
There are no provision for an external audio input for movie recording. The Autofocus in Live View mode is slow, limited to contrast-detect only; and it has no Auto Focus option with Live View. It has a maximum frame rate of 4.5 frames per second that is lower than some competing models, but it’s more than satisfactory.

In Summary:
This is a fantastic camera for the enthusiast with a great feature list and perfect control placement on the body. The controls feel good. If you want a camera that does video, takes fantastic photos, has great features and are looking to upgrade to a great new Digital SLR, I think the Nikon will fit your bill perfectly. It’s designed for some serious shooting and a pleasure to use and there are great sales out there for this camera.

The camera’s low light shooting capability enables you to achieve clear, natural images in darker conditions, with an ISO range of 100-6400 that can be further expanded to 12800.

The T3i can shoot up to 3.7 frames per second (fps) shooting at speeds of up to 1/4000 sec. With a range of automatic shooting modes, you’ll be able to capture full HD 1080P video that even beginners can use instantly, thanks to a Feature Guide as part of the user interface to help you develop your basic photo knowledge and skills.

Technical Specifications
* 18-megapixel CMOS sensor
* Scene Intelligent Auto mode
* Full-HD EOS Movie at 1080P
* On-screen Feature Guide
* 3.7fps continuous shooting
* Wide-area 9-point Autofucus
* 1,040k-dot variable-angle (3.0î) screen
* Basic + and Creative Filters†
* Built-in wireless flash control

Pro’s
* High image quality
* High ISO performance
* Rear rotating LCD screen
* In camera processing features Creative Filters
* Remote flash firing capability

Con’s
* Camera is a bit noisy in the continuous shooting mode
* Does not have a PC sync flash socket to plug in PC sync cords for off camera flash use
* Since the camera is fairly new to the market, there are not any appreciable negatives at this time

Summary
The EOS Rebel T3i features a bright, high resolution, flip-out Vari-angle 3.0-inch Clear View LCD monitor for shooting at a variety of angles. By simply rotating the monitor, you can hold the camera directly overhead for above-the-crowd shots at concerts, or hold the camera at a low angle for kids and pets. By rotating the LCD monitor fully, the EOS Rebel T3i becomes the ideal camera for self-portraits.

The Basic + Function modes allow even the novice photographer to use the basic automatic camera settings to make adjustments to the scenes ambiance such as vivid, soft, warm and several other levels. This is a step up from point and shoot cameras and meant for the beginning photographer.

* The Soft Focus effect filter helps dramatize an image and smooth over shiny reflections.
* The Grainy Black and White filter can give a different nostalgic perspective to any shot.
* Canon’s filter deliberately adds vignetting and color shift for a creative option when shooting a colorful scene.
* Users can also make a scene appear like a small-scale model, simulating the look from a tilt-shift lens, with Canon’s Miniature Effect filter, great when shooting any scene from a high vantage point.

I would say that the T3i is a great stepping stone for the photographer that wants to get away from the simple point and shoot camera. One that allows them to get away from the full-program mode of these simple cameras and give them some creativity, yet not overwhelm them all at once. This camera keeps it simple, yet allows one to opt for shutter speed, aperture settings and advance their photographic skills without breaking the bank.
