The new standard in digital photography has arrived with the Sony alpha DSLR-A900. Packed with features, this flagship DSLR is the first alpha to incorporate a 35mm full frame image sensor and 24.6-megapixel resolution. It also incorporates the world's first body-integrated, full-size SteadyShot INSIDE image stabilization technology. You'll also experience a larger capture area, improved wide-angle performance and tighter depth of field control with the new full frame Exmor CMOS image sensor. Equipped with Dual BIONZ imaging processors, the alpha A900 delivers continuous shooting up to 5 fps with superb image quality and ultra-low noise. The A900 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.
Photo.net Review Excerpt
Earlier this year Sony said they were working on a 24MP full frame DSLR with built-in image stabilization and they intended to bring it to market by the end of 2008. Well, they did! The Sony Alpha A900 is just that camera, and what’s equally noteworthy is that the price is “only” $3000. When you consider that the only other current high pixel count full frame DSLR is the $8000 Canon EOS 1Ds MkIII, the $3000 price tag seems almost cheap. Nikon’s new full frame DSLR, the D700, is also $3000, but it has a 12MP sensor and Canon’s venerable EOS 5D full frame DSLR (which also has a 12MP sensor) currently sells for around $2200. The Sony Alpha A900 certainly sets a new price/specification standard, at least on paper.
If a 24MP full frame DLSR for $3000 wasn’t enough, Sony added in-body stabilization via sensor shift technology. The specifications indicate higher performance than the system found on their crop sensor DSLRs and they say that it should offer up to 4 stops of stabilization. The obvious advantage of in-body stabilization is that you only pay for it once, and every lens mounted on the camera becomes part of a stabilized system. That means that all wide and normal primes become stabilized, something currently not possible with Canon and Nikon’s approach of putting stabilization in the lens rather than the camera body.
The Alpha A900 uses dual image processors to deal with the large amount of data, which the sensor generates and enable a continuous shooting rate of 5 frames/sec. The ISO range is 200-3200, expandable to 100-6400 via a custom function. While not as wide a range as the Nikon D700 (100-25,600), it’s probably as much as most photographers will need.
