Film-Advance Lever
The film-advance lever simu ltaneously advances the film, cocks the shutter and operates the frame counter. It also switches on the exposure meter in the Photomic finder. To advance the film, stroke the lever with the right thumb in a single stroke (or series of strokes) totaling only 120°. A built-in locking device prevents the shutter from being released unless it is fully cocked and the film advanced a full frame. At the completion of film advance, release the lever and it will return to the 20° standoff position ready for shutter release.
Note : Do not apply pressure to the film-advance lever while making an exposure .
Frame Counter
The frame counter operates automatically to show how many frames have been exposed. When the camera back is opened for loading, the cou nter is reset to the "5" (start) position, two frames before "0". Once the camera is loaded and the back closed, each film-advance/ shutter-release sequence will cause the frame counter to advance one position until the maximum 20 or 36 frames have been exposed. The dial of the frame counter is calibrated with dots (for odd numbers) and figures (for even numbers), and with settings of "5," "12," "20" and "36" in red.
