Face AiAF
• Detects people’s faces and sets the focus, exposure (evaluative metering
only) and white balance (
only).
• When the camera is pointed at subjects, a white frame appears on the
face the camera judges to be the main subject, and gray frames (max. 2)
will appear on other faces. When the shutter button is pressed halfway, up
to 9 green frames will appear on faces on which the camera focuses.
However, if either Servo AF (p. 91) or Continuous AF (p. 152) is set to
[On] and no faces are detected, the AF frame will appear in the center.
Changing the AF Frame Mode
You can switch between AF frames by pressing the button followed
by the ¤ button.
• If a face is not detected or only gray frames (no white frame) appear, up
to 9 green frames will appear on the areas the camera focuses on when
the shutter button is pressed halfway.
• Examples of faces that cannot be detected:
• Subjects that are far away or extremely close.
• Subjects that are dark or light.
• Faces turned to the side or at a diagonal, or faces with a portion hidden.
• The camera may mistakenly identify non-human subjects as a face.
• If the camera cannot focus when you press the shutter button halfway,
the AF frame will not appear.
