This option determines how long the monitor remains on if no
operations are performed during menu display and playback
(Playback/menus), while photographs are displayed in the
monitor after shooting (Image review), and during live view
(Live view), and how long the standby timer, viewfinder, and
information display remain on when no operations are
performed (Standby timer). Choose shorter auto-off delays to
reduce the drain on the battery.
