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) total-
ing
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.
