Mirror Lockup

Mirror lockup is enabled with C.Fn-12 (p.106). This prevents mirror- caused vibrations which may blur the image during close-ups or when a super telephoto lens is used. To set this Custom Function, see “Selecting and Setting a Custom Functions” on page 96. When mirror lockup is set, the camera operates as follows.

When using mirror lockup, Remote Switch RS-80N3 (sold separately) is recommended.

1 Press the shutter button completely.

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.

2Release the shutter button and press the shutter button completely again to take the picture.

The picture is taken and then the mirror goes back down.

• In very bright light such as at the beach or ski ground 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 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 film advance mode will be single-frame shooting regardless of the current film advance mode.

If mirror lockup is used with the self-timer, pressing the shutter button completely the first time will lock up the mirror and release the shutter 10 seconds or 2 seconds later (depending on the delay time selected).
