Wide AF area
Capture your subject anywhere in the frame. 4D FOCUS activates AF points across a wide area, so the camera can detect subjects throughout the entire frame, instead of just the center.
4D FOCUS instantly detects the distance to your subject and focuses quickly and accurately with advanced AF algorithm, so you never miss decisive moments.
Never lose sight of your subject. Our AF algorithm stays focused on the action, and even predicts your subject's next move, without getting distracted by any obstacles in the frame.
