Although using the self-timer or Remote Switch can prevent camera shake, using mirror lockup to prevent camera vibrations can also help when you use a super telephoto lens or shoot close ups.

When C.Fn III -15 [Mirror lockup] is set to [1:Enable] or [2:Enable: Down with SET] (p.172), shooting with mirror lockup is possible.

---

1 Focus the subject, press the shutter button completely and release it.

• The mirror will lockup and <> will blink on the top LCD panel.

2 Press the shutter button completely again.

• The picture will be taken.
• With [1] set, the mirror will go back down when the picture is taken.
• With [2] set, the mirror lockup will remain even after the picture is taken. To cancel the mirror lockup, press <SET>

• In very 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 bulb exposures, the self-timer, and mirror lockup in combination, keep pressing the shutter button completely (self-timer delay time + bulb exposure time). If you let go of the shutter button
• during the 2-sec./10-sec. self-timer countdown, there will be a shutterrelease sound. This is not the actual shutter release (no picture is taken).
• When [1:Enable] is set, single shooting will take effect even if the drive mode is continuous. When [2:Enable: Down with SET] is set, the current drive mode will take effect for the shooting.
• When the self-timer is set to <> or <>, the picture will be taken after 10 sec. or 2 sec. respectively.
• The mirror locks up, and after 30 seconds, it will go back down automatically.
• For mirror lockup shots, using Remote Switch RS-80N3 or Timer Remote Controller TC-80N3 ( optional) is recommended.
