, it is possible to lock
the mirror in the up position beforehand, and
at the desired instant release the shutter
without the usual accompanying mirror
movement.
Referred to as, "mirror lock-up operation," this
technique is extremely valuable when even
the slightest mirror vibration must be
eliminated. When the mirror rises, it usually
causes vibrations the very instant before the
shutter opens, creating a possible loss of
sharpness when working at high magnifica-
tions or with long shutter speeds. Conse-
quently, mirror lock-up operation is especially
useful when engaging in close-up
photography, using telephoto lenses, and
making long ("slow") exposures. Yet another
application is when trying to catch the peak of
at the desired instant release the shutter
without the usual accompanying mirror
movement.

action. By raising the mirror beforehand, the
shutter can instantly be released, totally
eliminating the time lag usually present
between the time the mirror completes its
upward swing and the time the shutter opens.
1. After screwing a cable release firmly into
the Mirror Lock-up Socket of the lens, the
socket will elevate slightly and the camera will
be ready for mirror lock-up operation.
2. Press the Cocking Lever as far as it will go.
Step 2 may either follow or precede step 1.
3. Depress the Shutter Release Button and
the mirror will rise, but the shutter will remain
closed.
4. Press the plunger of the cable release and
the shutter will operate.

• When you no longer need mirror lock-up
operation, remove the cable release.
Upon removing the release, the Mirror
Lockup Socket will retract and the camera
will return to normal shutter operation.
If you complete step 3 above, but remove
the cable release without making an
exposure (step 4), the shutter will be
released as soon as the cable release is
removed.
Even when using mirror lock-up operation,
everytime the shutter is cocked, the mirror is
relowered. Therefore, it is possible to check
the viewfinder before each frame is exposed.
A double cable release is both an available
and convenient accessory. Since one end of
the release screws into the Shutter Release
Button and the other end into the Mirror
Lock-up Socket, it is possible to use the
same release to raise the mirror and later
release the shutter.
The double cable release is particularly
valuable when using B exposures with mirror
lock-up operation. After pressing the shutter
release button to raise the mirror, detach the
cable release from the mirror lock-up socket.
At that instant the shutter will be released.
