Detects people’s faces, and then sets the focus, exposure 
(evaluative metering only), and white balance ([ ] only).
 
After you aim the camera at the subject, a white frame 
is displayed around the person’s face determined by the 
camera to be the main subject, and up to two gray frames are 
displayed around other detected faces.
 
When the camera detects movement, frames will follow moving 
subjects, within a certain range.
 
After you press the shutter button halfway, up to nine green 
frames are displayed around faces in focus.
 
If faces are not detected, or when only gray frames are displayed 
(without a white frame), up to nine green frames are displayed in 
the areas in focus when you press the shutter button halfway.
 
If faces are not detected when Servo AF (= 132) is set to [On], 
the AF frame is displayed in the center of the screen when you 
press the shutter button halfway.
 
Examples of faces that cannot be detected:
 -
Subjects that are distant or extremely close
 -
Subjects that are dark or light
 -
Faces in profile, at an angle, or partly hidden
 
The camera may misinterpret non-human subjects as faces.
 
No AF frames are displayed if the camera cannot focus when you 
press the shutter button halfway.
