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 [ C.Fn III - 13: Mirror lockup] is set to [1: Enable] shooting with mirror lockup will be possible.

---

1 Focus the subject, press the shutter button completely and release it.

• The mirror will swing up.

2 Press the shutter button completely again.

• The picture is taken and the mirror goes back down.
• In very bright light such as at the beach or 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 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 10-sec./2-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 set to continuous.
• The mirror locks up, and after 30 seconds, it will go back down automatically. Pressing the shutter button completely again locks up the mirror again.
• For mirror lockup shots, using the Remote Switch RS-80N3 or Timer Remote Controller TC-80N3 ( sold separately) is recommended.
• You can also lockup the mirror and shoot with the remote controller (sold separately, p.102). With Remote Controller RC-1, setting it to a 2-sec. delay is recommended for shooting.

NOTE:

Mirror lockup does not function in live view mode, as the mirror is already up.
