The α900 also offers a large, ultra-bright glass pentaprism viewfinder with 100 percent coverage, a 3.0-inch Xtra Fine LCD™ display and HDMI™ output with PhotoTV HD compatibility. The DSLR-A900 is a camera body only and does not include a lens.

Note: Sony α (alpha) lenses with the Digital Technology (DT) designation are not recommended for use with DSLR-A900. Although DT lenses can be used with α900, they can only realize a maximum of 11MP image size, and are not guaranteed to provide accurate Auto Exposure performance.

35mm full frame 24.6MP Exmor™ CMOS image sensor

The A900 features a 35mm full frame Exmor™ CMOS image sensor that is approximately 2.35x larger than the APS-C sized sensors found in many DSLR cameras. The result is a larger capture area, improved wide angle performance, and tighter depth of field control. In addition, its 24.6MP resolution maximizes the resolving power of your existing lenses and delivers sharper, higher contrast photos.

Ultra bright, 100% coverage glass pentaprism viewfinder

A large, ultra bright glass pentaprism viewfinder provides you with amazing clarity and high optical performance for tighter focus control. In addition, it offers viewfinder magnification of 0.74x, allowing you to see an image nearer to its actual size, as well as 100% field coverage for detailed framing work.

A supplied InfoLITHIUM® lithium-ion battery provides long-lasting performance, allowing you to capture approximately 880 images on a single charge7.

40-Segment Multi-Pattern Metering

A 40-segment multi-pattern metering system provides superior exposure control accuracy in a wide range of lighting conditions.

Dual Noise Reduction Processing

In addition to digitizing analog signals, the full frame Exmor™ CMOS image sensor also performs both analog and digital noise reduction. This on-chip dual noise reduction process aids in the high speed transfer of noiseless digital signals.

APS-C Size Capturing

In addition to full frame image capture, the A900 can also crop images to the APS-C size format, allowing the use of lenses designed specifically for APS-C sized image sensors5.

AF Micro Adjustment

AF Micro Adjustment allows you to fine tune focus for various lenses6. The A900 can store adjusted focus values for up to thirty lenses.

2EV Exposure Bracketing (3 exposures)

The A900 allows you to bracket up to three exposures in 2.0EV-step increments.

Review your images in stunning detail on the 3.0” Xtra Fine LCD™2 display (921k pixels). With photo-quality resolution of 270ppi (pixels per inch), you can identify any necessary focus or exposure corrections at the time of capture, rather than discovering them when you transfer your images to your PC.

Flagship design

The A900 features an impressive design befitting a premium flagship model. The simple form eschews ornamentation and exudes competence, while the iconic pentaprism design element conveys superior optical performance. The A900 also incorporates a distinctive cinnabar-colored ring circling the lens mount – a design element shared across every Sony® α; (alpha) DSLR camera.

Anti-Dust Technology

Changing lenses in a DSLR can allow dust to enter the camera -- so to help keep the CMOS imager cleaner for better pictures, the Sony® α; (alpha) DSLR-A900 utilizes both static-free anti-dust coating on the imager's filter and anti-dust vibration that automatically shakes the sensor to dislodge dust each time the camera is shut off.

Dual Card Slots

The A900 features a dual card slots and accepts both CompactFlash® and Memory Stick Duo™ Media (sold separately).

On-Chip Column A/D Conversion

Analog-to-digital signal conversion is performed by the full frame Exmor™ CMOS image sensor.

Eyepiece Shutter

The A900 includes a built-in eyepiece shutter which can be shut to help shield against entering light and prevent exposure errors.

Mirror Lockup Mode

Mirror Lockup Mode raises the main mirror before exposure to reduce vibration at shutter release, resulting in better performance during long exposure shots of fireworks, stars, etc.

Image Data Lightbox software

The Image Data Lightbox software4 included with your Sony® α; (alpha) DSLR helps you browse, rate, and compare your images, making it easier to select your favorites for further processing.

Convenient Button Placement

Concentrate on your shooting and make adjustments on the fly thanks to convenient button placement. The ISO and White Balance adjustment buttons are located on the top of the camera body near the shutter button for easy thumb operation.

SteadyShot INSIDE™ in-camera image stabilization:

Building on years of expertise, Sony has developed the world’s first body-integrated image stabilization solution for a full frame DSLR1. The SteadyShot INSIDE™ in-camera image stabilizer actually shifts the image sensor to compensate for camera shake without sacrificing image quality. The compensation effect is equal to as many as four shutter speed steps, giving you more creative freedom when shooting in low light. And, because it is integrated into the camera body, SteadyShot INSIDE technology works with all compatible α (alpha) system lenses.

Intelligent Preview Function

The Intelligent Preview function allows you to see the effects of manual adjustments to exposure value, shutter speed, aperture, Dynamic Range Optimizer and White Balance before you take the shot, so you can determine the optimum settings before you take the shot, instead of losing time to trial-and-error.

Precise and fast 9-point AF system w/ 10 point assist

A high-performance autofocus system uses 9 focus points (center dual-cross type) and 10 assist points to deliver fast and precise focusing.

Moisture/dust-resistant design

Sealed viewfinder optics and rubber gasket surrounds on all buttons, dials, and switches help resist the entry of dust and moisture into the camera, and allow for safe use in a wide range of environments.

Durable Shutter Design

The shutter mechanism in the A900 is designed to achieve shutter speeds up to 1/8000 seconds and proven for 100,000 cycle operation.

Dynamic Range Optimizer

To recover details in dark or bright areas of the image, the A900 provides multiple levels of Dynamic Range Optimization: Standard mode, to improve shadow detail using standard gamma curves; Advanced Auto mode, allowing you to select any of 5 DRO correction levels, or DRO Advanced Bracketing, which automatically takes three shots at different DRO levels with a single shutter press.

F2.8 Sensor

The autofocus system in the A900 features a highly accurate F2.8 sensor for improved focus precision when using lenses faster than F2.8.

Viewfinder magnification of 0.74x

Viewfinder magnification of 0.74x lets you see your subjects nearer to actual size.

Optional Focusing Screens (sold separately)

User-replaceable focusing screens for shooting specific subject types can be purchased as optional accessories.

Affordable Beast of a Camera I have Owned the A700 since it first came out. I have a long relationship with Sony products and I have never been disappointed. Before I got into the DSLR many of my friends were either Nikon or Canon users so when I purchased the Sony they all laughed at me. Sony took over Minolta which was a leader in the camera industry. With Minolta's experience and Sony's ability to think outside the box in terms of Technology I knew it would be a force to be reckoned with and has emerged in the DSLR market as a Solid #3. I have never been disappointed with the A700 so the choice to purchase the A900 was a no brainer. Being a nature Photographer I need something that will be bulletproof and provide alot of bang for the Buck. The closest camera to the A900 in the price range is the Canon 5D MkII. There was a 49/51% split amoug most professional reviews with Canon slimly edging out the A900 5 stars to 4.5... probably due to the HDvideo feature on the Canon... I have just purchased it so I am still learning more and more but in 10 shoots in 2 weeks I have not had any issues. Snow and Subfreezing temperatures have not slowed this beast down. I love the weight and with the Vertical Grip it is huge! I also have the A55 and I actually perfer the weight for a steady shot... Speaking of Steady shot having the feature on the body makes for less expensive lenses nearly 1/2 price in some cases and also using older minolta lenses and having the image stability available is a huge plus. February 13, 2011
The Alpha 900 - A Beast of a Camera With the arrival of the Alpha a900, Sony is officially paving the way for innovation in the DSLR market. Although I made the plunge in May 2010, about a year and half after it was introduced, I can easily say that this has been the best technology purchase I have ever made. The QuickNavi menu made learning the functions of the camera a breeze. Its magnesium alloy case along with its dust-proofing makes it perfect to use in a variety of environments: be it cold or warm. The 100% viewfinder is very bright and makes it easy to lock focus properly on your subject. With the install of Firmware Version 2.0, Auto-Focus is significantly quicker and more precise. The Alpha 900's best feature by far is it's 24.6 MP Exmor CMOS sensor which makes it the world's highest resolution full-frame digital SLR on the market ... In simple terms, the detail it is capable of offering is incredible. Image quality is out of this world. It is important to understand that the Alpha 900 is indeed a professional camera - intended to be used by either professional photographers or enthusiasts who are passionate about photography like me. In no way is this a camera that should be undermined ... It is capable of competing with the high end cameras of any SLR system. All in all the Alpha 900 is a camera that paving way in terms of image quality in the DSLR market all the while staying true to Konica Minolta's legacy of professional imaging. When paired with high quality Carl Zeiss and G Lenses, this camera delivers class leading image quality and handling. Once again great job SONY for delivering an outstanding camera! January 26, 2011
Finally took the plunge.... I've owned and enjoyed using my A700 since the day they were released, and kept telling myself there was no need to change. Then, I had the opportunity to handle and play with an A900, and "POW!" that was it. The viewfinder! What an utter delight. The styling, while not one of my top five reasons for making this purchase carries me back to my beloved Minoltas of days gone by. Features and option controls, I don't know where to start; controls that my fingers simply fall into place on. The logical control layout is a subject of its own. Today was my first field use at a water polo tournament, and all the surprises were pleasant. I used it with the vertical grip which I also had on my A700. I was able to get each shot I wanted, using the 24-70Z or 135 f1.8Z. In all a sign of much great shooting yet to be done! Thank you Sony. April 18, 2009
Superb! I had a Cannon for decades - it broke and they did not make the same model, thankfully! I went with a Sony and over the course of 10 years I have been so pleased that I have worked my way up. Having the a100, a 55 now the a900. I don't think I will ever have another camera! Very impressed with the constant strive to improve on already something great. The weight is only downfall for beginning to have trouble with my thumbs so hope to see that improve in the years ahead! March 12, 2012
