How to use mirror lockup on the EOS 1D Mark II, EOS 1D Mark II N, and EOS 1Ds Mark II.
Solution
Mirror lockup is enabled with C.Fn-12. This prevents mirror vibrations which may blur the image during close-ups or when a super telephoto lens is used. Set Custom Functions with <>.
1. Press the shutter button completely.
The mirror will lock in the up position.
-
2. Again press the shutter completely.
The picture is taken and the mirror goes back down.
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 shutterrelease sound. This is not the shutter release (no picture is taken).
During mirror lockup, the drive mode will be single shooting <> 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 ( sold separately) is recommended.
