Sony Alpha 900 Full Description

TYPE:The new standard in digital photography has arrived with the Sony a (alpha) DSLR-A900. Packed with features, this flagship DSLR is the first a (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.

35mm full frame 24.6MP Exmor™ CMOS image sensorThe 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.

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 a(alpha)system lenses.
