Verdict

The Sony A900 is a high-end, full-frame DSLR featuring a 24.6-megapixel Exmor CMOS sensor, dual BIONZ image processors, and the world's first sensor-shift image stabilization system (SteadyShot INSIDE) in a full-frame camera. Paired with the versatile Sony 28-75mm f/2.8 SAM lens—which features a bright, constant f/2.8 aperture, 7-blade circular aperture, and a built-in Smooth Autofocus Motor—this combination offers fantastic resolution, low-distortion, a magnificent 100% coverage optical viewfinder, and 5 frames per second continuous shooting. However, key disadvantages include relatively high chroma noise at sensitivities above ISO 400, lack of Live View or movie recording capabilities, the absence of weather sealing on the lens, and soft corner sharpness at maximum aperture.
