Mirror Lockup - Canon EOS-1V HS Instructions Manual

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.
• 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).

button completely again locks up the
mirror again.
2
