E: Selecting the AF Mode

If focus cannot be achieved, the focus confirmation light <o> in the viewfinder will blink. If this occurs, a picture cannot be taken even if the shutter button is pressed completely. Recompose the picture and try and focus again. Or see “When Autofocus Fails” (p.86).

If the [2Beep] menu is set to [Off], the beeper will not sound when focus is achieved.

Focus Lock

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.

AI Servo 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.

AF is also possible by pressing the <p> button.

Focus Tracking with AI Servo 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 (p.84), 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 the Area AF.

With a manually selected AF point, the selected AF point will focus track the subject.

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.
