last for about a half year, and the silver
oxide batteries for about one year.
When the temperature is extremely low.
Q : I pressed the shutter release button with the
selector dial at the "OFF" position. Will the
photograph be properly exposed?
A : Even at the "OFF" position, the camera's
circuits will be activated for a proper ex-
posure. Recommended to develop the film
and
see.
Q : When set at the "AUTO" position, the actual
shutter speed is much slower than the one
indicated in the viewfinder. Why does this
happen?
A : If film is not loaded or the film surface is
not properly positioned behind the shutter,
the
speed
will
be
slower
than
that
indicated
in the viewfinder.
Q : What batteries should I use?
A : Use two 1.5V alkaline-manganese batteries
LR44 (A76) or two silver oxide batteries
SR44 (Eveready EPX-76 or equivalents).
Batteries of a different type (1.3V mercury
batteries) cannot be used, though they may
be of the same size.
Q : A shadow appears darkening the central area
of the viewfinder. Why does this happen?
A : This is quite usual when a lens with a maxi-
mum aperture smaller than F5 is mounted
on the camera, and the preview button is
pressed with the diaphragm closed down
beyond F5. There is nothing wrong with
the microprism.
Q : If I return the selector lever to the ON posi-
tion, while the self-timer in operation, what
will become of the shutter?
A : The shutter will be released. After the use of
the self-timer, make it a point to return the
selector lever to original position.
Q : While I was operating the Winder 2, the light
in the viewfinder went out... why?
A : The
light
goes
out in 90
sec.
even
the
selector
lever is ON, in order to save the batteries from
unnecessary consumption. Touch the ac-
tivator switch lightly, and the light is on
again.
