Limiting Autofocus to Faces
While using autofocus, you can limit the autofocus function only to cases when a subject’s face is
detected and use manual focus for all other scenes. The camcorder will also adjust the brightness
when focusing automatically on the subject’s face.
Set an assignable button to [~ Face Only AF] (A 97) and press the button.
• ~ appears on the screen.
NOTES
• The camcorder may mistakenly detect the faces of non-human subjects. In such case, turn face
detection & tracking off.
• When face detection is activated, the slowest shutter speed used by the camcorder is 1/30 (1/24 if
the frame rate is set to 23.98P).
• In certain cases, faces may not be detected correctly. Typical examples include:
- Faces extremely small, large, dark or bright in relation to the overall picture.
- Faces turned to the side, at a diagonal or partially hidden.
• Face detection & tracking cannot be used in the following cases.
- When the shutter speed used is slower than 1/30 (1/24 if the frame rate is set to 23.98P).
- When the digital zoom is activated at more than 80x zoom.
• Touching somewhere with a color or pattern unique to the subject will make it easier to track.
However, if there is another subject in the vicinity that shares similar characteristics to the selected
subject, the camcorder may start tracking the incorrect subject. Touch the screen again to select
the desired subject.
• In certain cases, the camcorder may not be able to track the subject. Typical examples include:
- Subjects extremely small or large in relation to the overall picture.
- Subjects too similar to the background.
- Subjects lacking sufficient contrast.
- Fast moving subjects.
- When shooting indoors with insufficient lighting.
