¡ 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.
¡ Bulb exposures cannot be used with the self-timer. During the self-timer
countdown, if you let go of the shutter button, there will be a shutter-
release sound. This is not the shutter release (no picture is taken).
¡ During mirror lockup, the drive mode will be single shooting (u) to
override the current drive mode (single or continuous).
¡ After 30 seconds, the mirror lockup will be canceled automatically.
Pressing the shutter button completely again locks up the mirror again.
¡ For mirror lockup, using Remote Switch RS-80N3 or Timer Remote
Controller TC-80N3 (both sold separately) is recommended.
