Since the LED display differs
with the finder in use, please
read the instructions supplied
with the f inder for correct usage
and reading.
B. Turn ON the main switch
and then stroke the shutter release button halfways. lf the
LED display in the finder lights

Attachment and Removalof Film Backs
The film back is a film chamber that can be attached or detached f reely f rom the main
body, thus permitting f ree exchange of f ilrn types, at all
times. Since the main body and
film back are always fully coupled, upon connection, always
turn the film winding crank
completely one time, upon attaching the film back. lf winding is not possible, all preparations for taking the picture have
been completed. lf winding is
possible, however, rotating the
f ilm winding crank until it stops
automatically takes care of the
i n c o m p l e t e da c t i o n , w h e t h e r u n cocked shutter or film not advanced. Th is means, of course,
that it's possible to choose the
film type most suited for the
shot, even midway in a roll.
An ASA/ISO f ilm speed dial
and an exposure compensation
dial are available on the film
backs. When used for setting the
film speed of the film loaded
in the film back, there is automatic coupling when f inders
with built-in exposure meters
are attached on the main body.
This will, of course, be very convenient when using films of different sensitivities in the film
backs.
iF Make full use of film back interchangeability, in the f ollowtng manner:1. Take full advantage of the
multi-format superiority of the
GS-l and use film backs in
many different formats, wh ich
will not only give you different
effects but will economize on
f ilm.
2. Take \/our pictures in color
and black-and-white, and in different film speeds, as required.
3. Keep a sufficient guantity of
preloaded film backs on hand
and speedy, continuous shooting will be possible.
4. Don't waste unsuitable film
used in a previous session but
simply load up a new film back
with the requiredfilm type.
5. The Polaroid Film Back can
be used for instant color or
black-and-white pictures, when
in a rush, or used for checking
composition or lighting effect,
before taking the actual picture.
{F Film backs are avaifable optionally and the type meeting
the requirernents of the photographer should be chosen.
www.orphancameras.com
A. To attach the film back to
the main body, simply insertthe
latches at the upper end of the
film back into attachment openings at the upper end of the
main body. Then, press the
lower end of the f ilm back
against the main body until it
locks securely.
* The dark slide must be withdrawn from its slit, upon attachment of the film back to the
main body, as otherwise the
shutter cannot be released.
@
B. The dark slide must be inserted into the dark slide slit,
f o r r e m o v i n gt h e f i l m b a c k f r o m
the main body. Insert, with the
@ mark at the top, as illustrated, and then pushin all the way.
C . D e p r e s st h e f i l m b a c k r e l e a s e
button and the lower end of the
film back can be removed, as
illustrated.Simply shift the f ilm
back up slightly and pull it
away.
* There is danger of the film
back becoming detached from
the main body, if the dark slide
is left in its slit while the camera
i s b e i n g c a r r i e d . T h e r e f o r e ,m a k e
it a rule to withdraw the dark
slide whenever the film back is
attached to the main body.
* The dark slide cannot be
withdrawn from the film back,
when the film back is detached
from the main body.

both straps rnust be of the same

The battery supplies power for
the various electronic control
mechanisms incorporated in the
Zenza Bronica GS-l. When used
incorrectly, there is possibility
of the wrong exposure being set
to the camera and/or the camera
not operating.
Be sure to use and store the
battery correctly for obtaining
optimum performance from it
at all times.
* Take the battery out of the
battery chamber when storing
the camera.
* Leaving the battery in the
camerafor a long time, without
using it, oan lead to leakage
problems and result in poor
contact.
Discard a battery with leakage
or corrosion and thoroughly
clean out the battery chamber,
before inserting a new battery.
* Clean the contacts of the
battery chamber and battery
with a soft cloth. Don't use

(A54414LR44) is used with the
Zenza Bronica GS-l. Both have
very good cold weather resistance. However, there is a tendency for performance to droP
when the temperature falls be(32' F ). Therefore,
low ooc
make it a rule to use a new battery and/or keep replacement
batteries on hand for shooting
outdoors in f reezing weather.
Keep the battery (and camera)
under cover, next to the body,
and load just before beginning
