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.
