Film-Advance Lever; Frame Counter - Nikon F2AS Photomic Instruction Manual

Film-Advance Lever
The film-advance lever simultaneously 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) total-
ing only 120°. A built-in locking device prevents the
shutter from being released unless it is full y 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 load ing, 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 nCmbers) and figures
(for even numbers), and with settings of "5," "12,"
"20" and "36" in red.
