AF mode
(Single-shot AF)
In this AF mode, the focus is locked when you press the
shutter button halfway down. This mode is used when
shooting a motionless subject.
(Direct Manual Focus)
In this AF mode, you can manually fine-tune the focus after
using the autofocus function. This mode is used when an
unwanted subject comes into focus in macro recording, etc.
(Automatic AF)
This AF mode automatically switches between single-shot
AF and continuous AF, depending on the subject’s motion. If
the subject is in motion, the camera continues to focus while
the shutter button is pressed and held halfway down. If the
subject is motionless, the focus is locked when the shutter
button is pressed and held halfway down. This is a general
purpose AF mode suitable for portraits, group pictures,
snapshots, landscapes, etc.
