Take the picture.
Check the focus and exposure, then
press the shutter button completely to
take the picture (p.298).
Focusing on a subject other than a human face
• Tap on the subject (or spot) where you want to focus.
• Press <
9
> or <
0
> and the AF point < > will appear on the
screen. Then use <
9
> to move the AF point over the target
subject.
• Once the AF point < > 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.329) 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.
AF is not possible with a face or subject along the periphery. Aim the
area frame over the subject and focus.
The size of the AF point changes depending on the subject.
