When
No
Film
is
Loaded
in
the Camera
Even when
the
film
wind crank is
turned,
the
number
in
the
exposure
counter remains
at
"0".
In
this
case,
if
the
multiple
exposure
button
is
set on
"SINGLE,"
the
shutter
release
button
cannot be depressed.
However, when a
take·up spool is
in
the
take-up spool chamber, although
no
film
is loaded,
the
counter
may
be advanced (depending upon
the
type
of
spool). In
this
case, roller
connected
to
a
film
will
run idle,
causing wear on
the
roller and
provo
ing
undesirable
to
turn
the
film
wind
crank in
this
condition.
For certain lens·shutter assemblies,
the
release lever
for
the
shutter
itself
can be depressed many
times
even
though
the
shutter
is
not
cocked,
the
same
as
the
80mm
f/
3.7
lens. (When
the
shutter
is
not
cocked,
the
shutter
blades do
not
open).
When using
this
type
of
lens
shut
-
ter,
if
the
shutter
button
is depressed
without
cocking
the
shutter
, no pic·
ture
will
be recorded on
the
film.
Concerning
the
unopened
shutter
blades, even
though
the
shutter
is
cocked
manually,
the
shutter
button
will
not
operate due
to
action
of
the
double·exposure·preventing device. In
this
case, also, set
the
multiple
ex-
posure
button
tiangular
mark
toward
"MULTI"
and depress
the
shutter
button,
or
release
the
shutter
by
pushing
the
release lever on
the
lens·
shutter
assembly.
250mm
f/6.3
and
80mm
f/3.7
lenses:
Shutters
of
these lenses have no
self-cocking system, requiring
the
shutter
to
be set manually
after
each
film
advance.
