Its physical shutter, a key of any high-end DSLR, is an afterthought. Instead of being a limitation, however, it allows the Sony A9 Camera to do things the D5s and 1Ds of the world can't. At its core is the world's first stacked full-frame CMOS sensor, which puts memory onboard the sensor to enable processing that's up to 20x faster than previous Sony full-frames. Paired with a new Bionz X processing engine, it can make up to 60 auto focus and exposure calculations per second and shoot 20 stills per second. The hybrid AF system has 693 phase detection points and thanks to the fully electronic shutter, you can follow the action without any blackout through the Quad-VGA OLED EVF. Other notable features include a 5-axis image stabilization system, a maximum shutter speed of 1/32,000 sec., 24.2-megapixel resolution, and 4K video capture.
