Option Description
A Single AF
(default setting)
Focus is locked when movie recording starts.
Select this option when the distance between the camera and the
subject will remain fairly consistent.
B Full-time AF
The camera focuses continuously.
Select this option when the distance between the camera and

camera focusing may be heard in the recorded movie. Use of
