Choose when the control panel and button backlights light.
• If [ OFF ] is selected, the backlights will light when the power switch is
rotated to D . The backlights turn off when the shutter-release button
is pressed.
• If [ ON ] is selected, the backlights will light while the standby timer is
active. Note that this increases the drain on the battery. The backlights
will turn off while the shutter-release button is pressed, but will turn
on again when the button is released.
