In very bright places 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 bulb exposures, the self-timer, and mirror lockup in
combination, keep pressing the shutter button completely (2 sec. self-
timer + bulb exposure time). During the 2-sec. self-timer countdown, if
you let go of the shutter button, there will be a shutter-release sound.
This is not the shutter being released (no picture is taken).

During mirror lockup, the drive mode will be set to single shooting
regardless of the current drive mode setting (single or continuous).

completely and the shot will be taken 2 sec. after the mirror goes up.
