c: Timers/AE Lock

c1: Shutter-Release Button AE-L

At the default setting of Off, exposure only locks when the AE-L/AF-L
button is pressed. If On is selected, exposure will also lock when
the shutter-release button is pressed halfway.

c2: Auto Meter-off Delay

This option controls how long the camera
continues to meter exposure when no
operations are performed. Choose from 4 s,
6 s, 8 s, 16 s, 30 s, 1 minute, 5 minutes,
10 minutes, 30 minutes, or until the camera is
turned off (No limit). The shutter-speed and
aperture displays in the control panel and
viewfinder turn off automatically when the
exposure meters turn off.
Choose a shorter meter-off delay for longer battery life.
