Canon EOS40D Mirror LockupN, Press the shutter button completely again, Mirror will swing up

Mirror LockupN

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.

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 automatically.

For mirror lockup shots, using Remote Switch RS-80N3 or Timer Remote Controller TC-80N3 (both sold separately) is recommended.
