One-Shot AF for Still Subjects

This AF operation is suited for still subjects. When you press the shutter button halfway, the camera will focus only once.

  • Viewfinder shooting

    • Once a subject is in focus, the focusing AF point (1) flashes in red, the focus indicator (2) Focus indicator in the viewfinder lights up, and the camera beeps. The focus indicator Focus indicator blinks if the camera cannot focus.
  • Live View shooting

    • Once a subject is in focus, the focusing AF point turns green and the camera beeps. If focus is not achieved, the AF point will turn orange.

Note

  • If [Set-up: Beep] is set to [Disable], the beeper will not sound when focus is achieved.
  • The focus remains locked while you hold down the shutter button halfway, allowing you to recompose the image before taking the picture. This is called “focus lock.”
  • See Lens electronic MF when using a lens that supports electronic manual focusing.

AI Servo AF/Servo AF for Moving Subjects

This AF operation is suited for moving subjects. While you hold down the shutter button halfway, the camera will keep focusing on the subject continuously.

  • Viewfinder shooting (AI Servo)

    • Once a subject is in focus, the focusing AF point is displayed. The focus indicator Focus indicator in the viewfinder does not light up when subjects are in focus.
    • The beeper will not sound even when focus is achieved.
    • The exposure is set at the moment the picture is taken.
  • Live View shooting (Servo AF)

    • Once a subject is in focus, the focusing AF point turns blue.
    • The beeper will not sound even when focus is achieved.
    • The exposure is set at the moment the picture is taken.

Caution

  • Depending on the lens used, the distance to the subject and the subject's speed, the camera may not be able to achieve correct focus.
  • Zooming during continuous shooting may throw off the focus. Zoom first, then recompose and shoot.

AF Status Indicator (Viewfinder Shooting)

AF status indicator appears in the lower right of the viewfinder's field of view as the camera continues autofocusing while you press the shutter button halfway.

In One-Shot AF mode, the icon also appears while you press the shutter button halfway after the camera has focused on a subject.

Note

  • You can change the display position of the AF status indicator to outside the viewfinder's field of view ().
