f: Selecting the AF ModeN

If focus cannot be achieved, the focus confirmation light <o> and AF status indicator <e> in the viewfinder will blink. If this occurs, the picture cannot be taken even if the shutter button is pressed completely. Recompose the picture and try to focus again. Or see “When Autofocus Fails” (p.110).

If [z1: Beep] is set to [Disable], the beeper will not sound when focus is achieved.

After achieving focus with One-Shot AF, you can lock the focus on a subject and recompose the shot. This is called “focus lock”. This is convenient when you want to focus a subject not covered by the Area AF frame.

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.

When the AF area selection mode is set to 61-point automatic selection (p.72), 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 <o> in the viewfinder will not light up.

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 a still subject starts moving.

After the subject is focused in One-Shot AF mode, if the subject starts moving, the camera will detect the movement and change the AF mode automatically to AI Servo AF.

When focus is achieved in the AI Focus AF mode with the Servo mode active, the beeper will sound softly. However, the focus confirmation light <o> in the viewfinder will not light up. Note that focus will not be locked in this case.
