Sony’s flagship SLR boasts 24.6 megapixels on a full frame sensor with in-body Image Stabilization shooting at up to 5 frames per second. The “Exmor” CMOS image sensor is ~2.35x larger than typical APS-C size sensors, and the large capture area allows for more sharpness, tonal graduation, and depth of field control.
The 3 inch, 920,000 pixel LCD provides amazing resolution at the time of capture and provides superb feedback when shooting with Live View. It also provides an ‘intelligent preview’ function that allows you to see the effects of changes in shutter speed, aperture, etc. before you take the shot.
Sometimes overlooked in all the other features is the fact that the A900 has a very bright, 100% viewfinder. It has 9 primary focus and 10 focus assist points and provides a cross-type, f/2.8 center focus point. It also has dual card slots accepting either Compact Flash or Memory Stick Duo media. Together with batteries and a memory card it tips the scales at ~2 lbs (900g).
