AI Serve AF for Moving Subjects
This AF mode is for moving subjects when the focusing distance
keeps changing. While you hold down the shutter button halfway,
the subject will be focused continuously.
® The exposure is set at the moment the picture is taken.
® When the AF point selection (p.78) is automatic, the camera first
uses the center AF point to focus. During autofocusing, if the subject
moves away from the center AF point, focus tracking continues as
long as the subject is covered by another AF point.

AI Focus AF for Automatic Switching of AF Mode
AI Focus AF switches the AF mode from One-Shot AF to AI Servo
AF automatically if the still subject starts moving.

starts moving, the camera will detect the movement and change the
AF mode automatically to AI Servo AF.
