Mirror Lockup

mirror in the up position prevents mirror-caused vibrations that can blur the
image during close-up or telephoto shooting.
• When using mirror lockup, Remote Switch RS-60E3 (sold separately) is
recommended.

In 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 mirror lockup with the self-timer for a bulb exposure, there will be a
shutter release sound when you let go of the shutter button during self-timer
operation. This is not the sound of the shutter release.
During mirror lockup, the film advance mode (-»page 71) 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 lime will lock up the mirror and release the shutter 10
seconds later.
