- ONE SHOT : One-Shot AF
- AI FOCUS : AI Focus AF
- AI SERVO : AI Servo AF
For further information on the AF mode, see bellow.
[One-Shot AF] for Still Subjects Suited for still subjects. When you press the shutter button halfway, the camera will focus only once.
- When focus is achieved, the AF point which achieved focus will flash briefly in red, and the focus confirmation light [
 ] in the viewfinder will also light.
- With evaluative metering, the exposure setting will be set at the same time focus is achieved.
- While you hold down the shutter button halfway, the focus will be locked. You can then recompose the shot if desired.
NOTE
- If focus cannot be achieved, the focus confirmation light [
] 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 to focus again. Or see Or refer to the Related information "Difficult subjects for AF (Auto Focus)".
- If the [
 Beep] menu is set to [Disable], the beeper will not sound when focus is achieved.
[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.
- When the AF point selection is automatic, 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 another AF point.
NOTE
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.
[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 the still subject starts moving.
After the subject is focused in the 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.
NOTE
When focus is achieved with AI Focus AF with the Servo operation active, the beeper will continue beeping softly. However, the focus confirmation light [
] in the viewfinder will not light up. Note that focus will not be locked in this case.
