Dual Pixel CMOS AF
When using the Canon EOS-1D X Mark III like a mirrorless camera, in Live View mode, autofocusing is performed by our renowned Dual Pixel CMOS AF system. This turns virtually every pixel on the camera’s sensor into an imaging pixel and a phase-detection AF pixel.
Dual pixel CMOS AF can operate quickly when shooting stills, tracking moving objects around the frame, and more smoothly when capturing video, allowing professional pull-focus effects from one object to another.
The implementation of Dual Pixel CMOS AF technology in the Canon EOS-1D X Mark III sees focus-capable pixels over the whole height of the frame and over 90 per cent of its width. Performance has increased to a level where it’s possible to shoot at 20fps with fast, accurate, continuous focusing. The same deep-learning AF algorithm that’s available when using the camera in viewfinder mode is available to Dual Pixel CMOS AF, so you can be confident that critical sharpness is being maintained on the object, animal or person being tracked.
