Sony's professional Alpha 9 camera line has been a testbed of innovation since its introduction. The Alpha 9 III continues this legacy. It's built around the world's first full-frame global shutter image sensor, a 24.6-megapixel stacked CMOS component that exposes and reads all pixels simultaneously, eliminating rolling shutter distortion and camera blackout while enabling burst speeds of up to 120 frames per second. A sensor that fast needs an equally advanced autofocus system, and it delivers with up to 120 times AF/AE focus calculations per second. It's paired with a BIONZ XR processor, 8.0 stops of optical 5-axis in-body image stabilization, and a max shutter speed of 1/80,000 second, with flash sync enabled across the shutter range with a compatible unit.
