Mirror Lockup

Mirror lock is enabled with C.Fn-3-1 (→124). This function raises the mirror and exposes the picture, in separate operations. It is useful for close-up shots or when using a super telephoto lens, where the mirror shock could affect the picture.

●When using mirror lockup, we recommend you use the Remote Switch RS-80N3 (sold separately).

2 fully again.

● The picture is taken, and the mirror goes back down.

● To take the picture again, repeat the procedure from step 1.

●During mirror lockup, do not point the camera at the sun. The sun’s heat can scorch and damage the shutter curtains.

●If you use mirror lockup with the self-timer for a bulb exposure, there will be a shutter release sound when you release the shutter button during self-timer operation. This is not the sound of the shutter release.

● During mirror lockup, the drive mode (→67) is single-frame shooting regardless of the current setting.

●If you use mirror lockup with the self-timer, pressing the shutter button down fully the first time raises and locks the mirror, then releases the shutter 2 seconds later.
