Predictive AF

When a subject is approaching or retreating from the camera at a constant rate, the focusing function can track the subject and predict the focusing distance immediately before the picture is taken so that the shot will be in focus at the moment of exposure.

●When the AF point is selected automatically, the camera uses one of three AF points to focus on the subject. Tracking and predictive focusing is carried out using the camera selected AF point.

●When the AF point is selected manually (→57), the selected AF point tracks the subject.

AI Focus AF

AI Focus AF is set automatically in <> (Full Auto) mode. At the time of the shot, the camera automatically selects One-shot AF or AI Servo AF according to the state of the subject.

If the subject is focused in One-shot AF and the subject then begins to move continuously, the camera detects the movement, automatically switches to AI Servo AF, and focuses continuously as it tracks the subject.
