The Sony Alpha DSLR-A900 Digital SLR Camera incorporates 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. 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. 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 (alpha) system lenses.
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. 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.
