Choosing a Focus Mode

The following autofocus modes are available in live view:

AF-S

Single-servo AF: For stationary subjects. Focus locks when shutter-release button is pressed halfway. You can also focus by touching your subject in the monitor, in which case focus locks until you lift your finger from the display to take the photograph.

AF-F

Full-time-servo AF: For moving subjects. Camera focuses continuously until shutter-release button is pressed. Focus locks when shutter-release button is pressed halfway. You can also focus by touching your subject in the monitor, in which case focus locks until you lift your finger from the display to take the photograph.

To choose an autofocus mode, press the AF-mode button and rotate the main command dial until the desired mode is displayed in the monitor.

Choosing an AF-Area Mode

The following AF-area modes can be selected in live view:

!

Face-priority AF: Use for portraits. The camera automatically detects and focuses on portrait subjects; the selected subject is indicated by a double yellow border (if multiple faces are detected, the camera will focus on the closest subject; to choose a different subject, use the multi selector). If the camera can no longer detect the subject (because, for example, the subject has turned to face away from the camera), the border will no longer be displayed. If you touch the monitor, the camera will focus on the face closest to your finger and take a photograph when you lift your finger from the screen.

5

Wide-area AF: Use for hand-held shots of landscapes and other non-portrait subjects. Use the multi selector or touch controls to move the focus point anywhere in the frame, or press the center of the multi selector to position the focus point in the center of the frame.

6

Normal-area AF: Focus on a selected spot in the frame. Use the multi selector or touch controls to move the focus point anywhere in the frame, or press the center of the multi selector to position the focus point in the center of the frame. A tripod is recommended.

3

Pinpoint AF: As for normal-area AF, except that a smaller focus point is used for pinpoint focus on smaller targets.

&

Subject-tracking AF: Position the focus point over your subject and press the center of the multi selector. The focus point will track the selected subject as it moves through the frame. To end tracking, press the center of the multi selector again. Alternatively, you can start tracking by touching your subject in the monitor; to end tracking and take a photograph, lift your finger from the screen. If tracking is already in progress, touching the monitor anywhere will cause the camera to focus on the current subject, and a photo will be taken when you lift your finger from the screen. Note that the camera may be unable to track subjects if they move quickly, leave the frame or are obscured by other objects, change visibly in size, color, or brightness, or are too small, too large, too bright, too dark, or similar in color or brightness to the background.

To choose an AF-area mode, press the AF-mode button and rotate the sub-command dial until the desired mode is displayed in the monitor.
