4. AF Modes The camera can autofocus in one of three modes: One-Shot AF, Al Focus AF, and Al Servo AF. Select the AF mode most suitable for the subject. Turn the AF mode dial and set the desired AF mode. The AF mode dial settings are explained below. One-Shot AF This mode is suited for still subjects. Since the picture cannot be taken unless the subject is focused, this mode helps prevent out-of-focus shots. Pressing the shutter button halfway activates the autofocus. When the active focusing point achieves focus, it flashes in red and the in-focus indicator lights in the viewfinder. The exposure is also set when focus is achieved. e!., If you keep pressing the shutter button halfway after focus is achieved, it will lock --Npiz the focus and the exposure setting. You can then recompose the shot without changing the point of focus and exposure. If the in-focus indicator in the viewfinder blinks, the picture cannot be taken. Either recompose the shot or follow the countermeasures explained in "5. When Autofocus Fails" on page 39. Al Focus AF In this mode, One-Shot AF is the normal AF mode. However, if the subject starts to move, the camera detects the subject's movement and switches to Al Servo AF automatically. When the focusing point selection is automatic and the center focusing point first focuses the subject, the camera switches to Al Servo AF if the subject moves to another focusing point in the viewfinder during autofocusing. 37
