Canon EOS60D18135ISKIT User Manual (en)

Although using the self-timer or Remote Switch can prevent camera 
shake, using mirror lockup to prevent camera vibrations (mirror shock) 
can also help when you use a super telephoto lens or shoot close ups 
(macro photography).
When [8C.Fn III -5: Mirror lockup] is set to [1: Enable], shooting 
with mirror lockup will be possible
Focus the subject, then press the shutter button 
The mirror will swing up.
Press the shutter button completely again.
The picture is taken and the mirror goes back down.
Mirror LockupN
In very bright light such as at the beach or a ski slope on a sunny day, 
take the picture promptly after mirror lockup.
Do not point the camera toward the sun. The sun’s heat can scorch and 
damage the shutter curtains.
If you use the self-timer and mirror lockup in combination with a bulb 
exposure, keep pressing the shutter button completely (self-timer delay 
time + bulb exposure time). If you let go of the shutter button during the 
self-timer countdown, there will be a shutter-release sound, but no 
picture will be taken.
When [1: Enable] is set, single shooting will take effect even if the drive 
mode is set to continuous.
When the self-timer is set to <Q> or <k>, the picture will be taken 
after 10 sec. or 2 sec. respectively.
If 30 seconds elapse after the mirror has locked up, it will go back down 
automatically. Pressing the shutter button completely again locks up the 
mirror again.
For mirror lockup, using Remote Switch RS-60E3 (sold separately) is 
recommended (p.124).
You can also lockup the mirror and shoot with a remote controller (sold 
separately, p.126). Setting the remote controller to a 2-sec. delay is
