Memo holder

As a reminder of the film type and the number of ex

posures on the roll in use, clip off the end of the film

carton and insert it into the memo holder.

Note:

At the "B"setting, unless you hold the shutter release button down

all the way, the shutter may close prematurely.

Shutter release button

Slight pressure on the shutter release button switches on
the exposure meter. Pushing the button all the way down

releases the shutter. The shutter release button is thread

ed at the center to accept a standard cable release.

When battery power fails, the F3's electromagnetically

controlled shutter ceases to operate. You cannot release

the shutter release button unless you use the backup
mechanical release lever ®.

To lock the shutter release button when the camera is not

in use, turn the power switch to the "OFF" position.
