Mirror Lock-up Photography

*To override the multiple expo- sure mode or to return to normal operation, be sure to return the lever’s White Dot against the white square and then advance the film. (If you forget you will continue to make multiple exposures on the same frame.)

This is an important feature when the tripod mounted camera is used at slow or long exposure times and particularly also with use of long telephoto lenses. It eliminates the possibility of even the slightest “mir- ror bounce” which may affect image sharpness.

Move the Mirror look-up Lever to the yellow ”M.UP” square, after you have composed and focused your picture. This will raise the mirror and the viewfinder image will be blacked out. After use, return lever to normal (white

square) position.

*When using the AE Prism

Finder, set the Shutter Speed Dial to “AEL”. Press the shutter re- lease halfway and then lock the mirror up. If set to “A” and the mirror is locked up, “LT” (long time) will appear in the finder dis- play and correct exposure cannot be obtained.

*When using a Leaf Shutter Lens, be sure to read the instructions accompanying it.
