I’ll always remember experiencing Canon’s ingenious Eye-control AF for the first time. It blew me away during a hands-on session with the Canon EOS R1 and Canon EOS R5 Mark II – Canon's latest mirrorless cameras for pros.
The autofocus feature is unique to Canon. Once you've calibrated it to your eye, you simply look through the viewfinder, and Eye-control AF selects the autofocus point based on where you're looking in the frame (the EOS R5 Mark II promo video below illustrates the feature, starting at 1:51).
