Using AF to Focus
2
Focus the subject.
Press the shutter button halfway and
the camera will focus the face
covered by the <
p > frame.
X When focus is achieved, the AF point
will turn green and the beeper will
sound.
X If focus is not achieved, the AF point
will turn orange.
If a face cannot be detected, the AF
point < > will be displayed and AF
will be executed at the center.
3
Take the picture.
Check the focus and exposure, then
press the shutter button completely to
take the picture (p.198).
If the focus is far off, face detection will not be possible. If the lens
enables manual focusing even while the lens focus mode switch is set to
<
AF >, turn the focusing ring to attain rough focus. The face will then be
detected and < p > will be displayed.
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, titled horizontally or diagonally, or partially hidden.
The < p > focusing frame may cover only part of the face.
When you press <
9
> straight down or press <
0
>, the AF mode will
switch to the Live mode (p.207). You can tilt < 9 > to move the AF point.
Press <
9
> straight down again or press <
0
> to return to the u (face
detection) Live mode.
Since AF is not possible with a face detected near the edge of the
picture, the <
p > will be grayed out. Then if you press the shutter button
halfway, the center AF point < > will be used to focus.
