(Face detection) Live Mode:

With the same AF method as the Live mode, human faces are detected and focused. Have the target person face the camera.

1 Display the Live View image.
  • Press the <> button.
  • The Live View image will appear on the LCD monitor.
  • When a face is detected, the <> frame will appear over the face to be focused.
  • If multiple faces are detected, <> will be displayed. Press the <> key to move the <> frame over the target face.
2 Focus the subject.
  • Press the shutter button halfway and the camera will focus the face covered by the <> frame.
  • When focus is achieved, the AF point will turn green and the beeper will sound.
  • If focus is not achieved, the AF point will turn orange.
  • If a face cannot be detected, the AF point < > will be displayed and AF will be executed at the center.
3 Take the picture.
  • Check the focus and exposure, then press the shutter button completely to take the picture
  • If the focus is way off, face detection will not be possible. If the lens enables manual focusing even while the lens focus mode switch is set to <AF>, turn the focusing ring to attain rough focus. The face will then be detected and <> will be displayed.
  • An object other than a human face might be detected as a face.
  • Face detection will not work if the face is very small or large in the picture, too bright or too dark, titled horizontally or diagonally, or partially hidden.
  • The <> focusing frame might cover only part of the face.

  • When you press the <> button, the AF mode will switch to the Live mode. You can press the <> key to move the AF point. Press the <> button again to return to the (face detection) Live mode.
  • Since AF is not possible with a face detected near the edge of the picture, the <> will be grayed out. Then if you press the shutter button halfway, the center AF point < > will be used to focus.
