Changing the AF Frame Mode

You can change the AF (Auto Focus) frame mode to match the conditions

you want to shoot.

Choose [AF Frame].

● Press the n button, choose the 4 tab,

and then choose the [AF Frame] menu item.

Press the qr buttons to choose an option.

● 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.

• 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

specific point.

• If a face is not detected and 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:

• 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.

• 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.
