Speed and Autofocus

The Sony delivers blistering performance with electronic continuous shooting reaching 30 fps alongside mechanical shooting at 10 fps. This high frame rate lets sports and wildlife shooters capture fleeting moments with ease.

Pre-burst capture buffers up to 1 s of frames before you fully press the shutter, ensuring you never miss the exact moment an action starts. Its advanced autofocus detects humans, animals, birds, insects, cars, trains, and airplanes automatically.

Image Quality and Stabilization

Equipped with a 50.1 MP full-frame sensor, the camera captures fine detail across its 3:2 aspect ratio. You can also create ultra-detailed composites using 4- or 16-shot pixel shift modes merged via desktop software.

Handheld shooting is much easier thanks to in-body image stabilization rated at 8.5 stops at the center, though it drops to 7.0 stops at the periphery. This stabilization allows for slower shutter speeds in low light without introducing blur.
