Operating Instructions

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 threaded 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.
Film advance lever
The film advance lever is specially contoured to fit the thumb and is coaxial with the shutter release button. It has
a 30° stand-off with a throw of 140° and may be operated in one complete stroke or a series of shorter ones.
