AI Servo AF for Moving Subjects



AI Servo AF for Moving Subjects

This AF mode is suited 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.

  • AF is also possible by pressing the <AF-ON> button.

Focus Tracking with AI Servo AF

If the subject approaches or moves away from the camera at a constant rate, the camera tracks the subject and predicts the focusing distance immediately before the picture is taken. This is for obtaining correct focus at the moment of exposure.

  • When the AF area selection mode is set to 61-point automatic selection, the camera first uses the manually-selected AF point to focus. During autofocusing, if the subject moves away from the manually-selected AF point, focus tracking continues as long as the subject is covered by the Area AF frame.

With AI Servo AF, the beeper will not sound even when focus is achieved. Also, the focus confirmation light <> in the viewfinder will not light up.
