Selecting the AF Mode★ • When focus is achieved, the focus confirmation light in the viewfinder will not light and the beeper will not sound. • If the focus confirmation light in the viewfinder blinks, it means focus has not been achieved. • Focus lock cannot be used. ∗ Predictive AF If the subject approaches or retreats 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 point selection is automatic, the camera first uses the center AF point to focus. If the subject moves away from the center AF point, focus tracking continues as long as the subject is covered by another AF point. The active AF point will not flash in red. • With a manually selected AF point, the selected AF point is used for predictive AF. • In the Eye Control mode, Eye Control Servo AF (p.49) will be used. As long as one of the AF points cover the moving subject, predictive AF will continue to track the subject as you follow it with your eye. With C.Fn-04-2, holding down the button will temporarily stop the AF operation in the AI Servo AF mode. (p.85) AI Focus AF for Automatic AF Mode Switching The AI Focus AF mode switches automatically from One-Shot AF to AI Servo AF if the subject starts to move. If focus is achieved in the One-Shot AF mode and the subject starts to move continuously, the camera will detect the movement and switch automatically to AI Servo AF to focus track the subject. 40
