d: Shooting/Display
d1: Beep
At the default setting of On, a beep will sound when the camera focuses in single-
servo AF (
5 or when shooting stationary subjects in 4 autofocus mode), while
the release timer is counting down in self-timer and delayed remote modes (pg. 66,
68), or when a photograph is taken in quick-response remote mode (pg. 68). The
beep will not sound when Off is selected.
This option is available in all shooting modes. The current setting
is shown in the control panel:
3 is displayed when the beep is on,
2 when it is off.
This option (available in all shooting modes) controls how long
the monitor remains on when no operations are performed
during playback, image review, or when menus or shooting
information is displayed. Choose from 4 s (the default for image
review), 10 s (the default for playback and shooting information),
20 s (the default for menus), 1 minute, 5 minutes, or 10 minutes.
Choose a shorter monitor-off delay for longer battery life.
Regardless of the setting chosen, the monitor remains on if no
operations are performed for about ten minutes when the
camera is powered by an optional EH-5a or EH-5 AC adapter.
