Changing the AF Frame Mode
87
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.
A frame will follow a moving subject within a certain range.
When the shutter button is pressed halfway, up to 9 green frames will
appear on faces that the camera focuses on.
You can choose the subject you want to focus on and shoot (p. 89).
Face Detect
If a face is not detected, or only gray frames (no white frame) appear, an
AF frame will appear in the center of the screen when you press the
shutter button halfway.
If a face is not detected when Servo AF (p. 91) is set to [On], the AF frame
will appear in the center of the screen when you press the shutter button
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 an angle, 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.
