Q
Locking the Mirror Upward
Whenever it is imperative to completely eliminate
all camera movement, you can lock the mirror in the
"up" position before taking a picture. This is
particularly necessary when the EF is mounted on a
microscope or a bellows unit, where the slightest
vibration of the camera is magnified many times in
the final photograph. After you have focused, lock
the multi-purpose lever in its stopped-down position
and take a meter reading. Then, turn the L-M lock
lever to the orange "M" position, which will flip the
mirror up and lock it there. Take the shot by using a
cable release to trip the shutter.
