Although using the self-timer or Remote Switch can prevent camera
shake, using mirror lockup to prevent camera vibrations can also help
when you use a super telephoto lens or shoot close ups.
When [8C.Fn III -7] (Mirror lockup) is set to [1:Enable] (p.160),
shooting with mirror lockup will be possible.
1 Focus the subject, press the shutter button completely
and release it.
XThe mirror will swing up.
2 Press the shutter button completely again.
XThe picture is taken and the mirror goes back down.
Mirror LockupN
In very bright light such as at the beach or ski slope on a sunny day, take
the picture promptly after mirror lockup.
During mirror lockup, do not point the camera lens at the sun. The sun’s
heat can scorch and damage the shutter curtains.
If you use bulb exposures, the self-timer, and mirror lockup in
combination, keep pressing the shutter button completely (self-timer
delay time + bulb exposure time). If you let go of the shutter button
during the 2-sec./10-sec. self-timer countdown, there will be a shutter-
release sound. This is not the actual shutter release (no picture is taken).
When [1:Enable] is set, single shooting will take effect even if the drive
mode is continuous.
When the self-timer is set to <j> or <l>, the picture will be taken
after 10 sec. or 2 sec. respectively.
The mirror locks up, and after 30 seconds, it will go back down
For mirror lockup shots, using Remote Switch RS-80N3 or Timer Remote
Controller TC-80N3 (both sold separately) is recommended.
