Autofocus Drive
There are two AF Drive options: Single or Continuous. These
drive options can be set by selecting Camera Operation>AF
Drive on the XF top screen or in the XF menu on the IQ back.
Single:
Focuses the lens once, after pressing the release button half-
way. Half-pressed stage locks the focus, allowing the photogra-
pher to recompose the image before fully depressing the shut-
ter. Autofocus is reactivated anytime by releasing and pressing
the half-press shutter release button again.
Continuous:
On half-press of the shutter release button the lens focuses,
while the AF system continues to monitor the subject. If the
subject moves, the lens will refocus to follow the subject. Press-
ing the release button to the second stage releases the shutter,
regardless of whether the subject is in focus or not.
AF Priority:
The AF priority can be set to prevent shutter release until the
subject is in focus. To change AF Priority access the Camera
Operation>AF Priority on the XF top screen or from the XF Menu
on the IQ back.
Focus Area:
To change from the default size AF area (outer rectangle) to
the smaller, center area AF, select the AF Area icon from the
XF top screen.
NOTE:
Depending on which lens you are using, the focus mode can be set on
the lens, either by turning the focus selector ring or by moving the AF/
MF focus ring forwards or backwards.
