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 takeup 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 prov-
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 triangular 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.
