 Mirror LockupN
 
Do not point the camera toward an intense light source, such as the sun 
or an intense artificial light source. Doing so may damage the image 
sensor or the camera’s internal components.
 
When shooting with mirror lockup in very bright light, such as at the 
beach or a ski slope on a sunny day, take the picture promptly after 
mirror lockup is stabilized.
 
During mirror lockup, shooting function settings and menu operations are 
disabled.
 
When [Enable] is set, single shooting will take effect even if the drive 
mode is set to continuous.
 
You can also use the self-timer with mirror lockup.
 
If approx. 30 sec. elapse after the mirror has locked up, it will go back 
down automatically. Pressing the shutter button completely locks up the 
mirror again.
 
When shooting with mirror lockup, using a tripod and Remote Switch RS-
80N3 or Timer Remote Controller TC-80N3 (each sold separately) is 
recommended (p.279).
 
You can also use a remote controller (sold separately, p.279) with mirror 
lockup. Setting the remote controller to a 2-sec. delay is recommended.
