Detects people’s faces and sets the focus, exposure (evaluative metering

When the camera is pointed at subjects, a white frame appears on the

will appear on other faces.

A frame will follow a detected face that is moving within a certain range.

When the shutter button is pressed halfway, up to 9 green frames will
appear on faces on which the camera focuses.

Center
The AF frame is locked to the center. This is effective for focusing on a

up to 9 green frames will appear on the areas the camera focuses on
when the shutter button is pressed halfway.

If the camera cannot focus when you press the shutter button halfway,
the AF frame will not appear.
• 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.
