Sony announces a9 24MP 20fps high-end full-frame sports camera Sony announced today the new A9 "Sports" camera, optimized for high speed capture (20 fps), no-blackout viewfinder, dual memory cards and double the battery life of the A7 (new battery, not reverse compatible). The first model has a back-lighted 24 MP sensor with ISO to 204,000. The viewfinder has twice the resolution (3 MP) and twice the refresh speed (120 fps) of the A7. Autofocus has over 600 sensing points in the focal plane, and is optimized for high speed acquisition and tracking down to f/11 (in Sony, the aperture closes to the preset value once focus lock is achieved). There is a built-in LAN connection for real time uploads to a control room or studio. The targeted marketplace for the A9 is clearly focused on the niche long held by the flagship cameras of Nikon and Canon. It is likely that an high resolution "R" model and high ISO "S" model will follow.
