Using AF to Focus (AF Method)
270
Focusing on a subject other than a human face
Press <
9
> or <
0
> and the AF frame < > will appear in the
center. Then use <
9
> to move the AF frame over the desired
subject. Once the AF frame < > achieves focus, it will track the
subject even if the subject moves or if you change the composition.
If the subject’s face is significantly out of focus, face detection will not be
possible. Adjust the focus manually (p.275) so that the face can be
detected, then perform AF.
An object other than a human face may be detected as a face.
Face detection will not work if the face is very small or large in the
picture, too bright or too dark, or partially hidden.
The <
p
> may cover only part of the face.
Since AF is not possible with a face or a subject detected near the edge
of the picture, the <
p
> or < > will be grayed out. If you press the
shutter button halfway in this situation, the subject will be focused on with
the FlexiZone - Single method.
The size of the AF frame varies depending on the subject or the setting
of [
z
4: Crop/aspect ratio ].
