Mirror Lockup

Mirror lockup is enabled with C.Fn-12-1. (p.149) 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 “Setting a Custom Function” on page 145. When mirror lockup is set, the camera operates as follows.

1

2

Press the shutter button fully.

sThe mirror will lock up.

After 30 seconds, it will go back down automatically.

Press the shutter button fully again.

The image will be captured and the mirror will go back down.

To take another shot with mirror lockup, start from step 1 again.

In very bright light such as at the beach or ski ground on a sunny day, shoot 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 actual shutter release.

When using mirror lockup, Remote Switch RS-80N3 (optional) is recommended. (p.76)

During mirror lockup, the single drive mode will take effect regardless of the current drive mode setting.

If the self-timer is used with mirror lockup, pressing the shutter button fully the first time will lock up the mirror, then the shot will be taken 2 seconds later.

LCD Panel Illumination

LCD panel illumination is provided.

The <> button turns the illumination of the LCD panel on or off. The illumination stays on for 6 sec. If you shoot while the panel is illuminated, the illumina- tion will turn off 2 seconds after shooting. If you take a bulb exposure while the panel is illuminated, the illumination will turn off immediately.

The illumination will remain on if you press any button for shooting or the Mode dial.
