The interchangeable film hacks for G0IIIAREX and C0NTAFLEX
permit chonging of different film types in one ccmero by doylight ond without the loss
of o single frome. You ore therefore instontly reody for every iype of subiect. Whether
you use block-ond-white or colour film, negotive or reversol, every emulsion is im-
mediotely reody for shooting on chonging the film bock. Thot olso mokes o second
comero body or o second comero unnecessory.
The interchongeoble bock fol<es the fllm in the usuol stondord cossette ond, ofter oll
exposures ore finished, the film is rewound into its cossette. Every interchongeoble bock
corries one indicotor for the film type ond one for the film speed, os well os o frome
counter showing the number of unexposed fromes still in hond. Thot cleorly identifies
the film octuolly looded in the interchangeoble bock.

booklet corefully before iooding your first film. Most of the operotions con however
be corried oui wilhout o film; so be sure to proctise lhem beforehond. Hondling the
interchongeoble bock will soon become so fomilior thot you will work with it olmost
instinctively.
l. loading the Film into the lnterchangeahle Baclr
l. Roise the boseboord locking keys (13, l5) of the interchongeoble bock ond turn them
  os for os they will go.
2. Pull out the dork slide (10) bV pressing in the lock (3) with the thumb ond gripping

the recess of the dork slide in the bottom with the index finger ond second finger.
3. Gently releose the retoining spring (9) over the ridge ond pull the shell (4) off the
   cossette chomber.
4. Open the cover of the toke-up chomber (.|2) by pushing it outwords by its grooves
  os for os it will go.
5. Insert the cossette into the cossette chomber; first however pull the film leoder bock
   into the cossette so thot only oboul 11/z inches protrude from the cossette slit. Push
   the film leoder, emulsion side upwords, through the slot on to the pressure plote (7)
  ond guide it underneoth the upper film guide (6). See fig. l.
6. Reploce the shell (4). The retoining spring (9) must positively engoge the pin on the
   shell. The cross bor of the film spool is visible through the opening in the bottom
   of the shell. Thqt indicotes whether there is o fllm in the interchongeoble bock.

'        7. Feed through the film leoder, without depressing the pressure plote (7), ond guide
           the film underneoth the lower film guide os well. Then push the film leoder into the
            slot underneoth the toke-up spool (8), ond feed it through until it comes right round
          the toke-up spool (B). Both film edges must run underneoth the film guides (5,6).
         To focilitote the process of feeding through, turn ihe ioke-up spool in the direction
           of the film feed by meons of the spool flonge (1'l). See frg.2.
         B. Turn the spool flonge (11) to bring the slot in the ioke-up spool (8) on top. Anchor
          the film with the second or third perforotion hole in the hook in ihe slot. Now
         wind up the trimmed film leoder by meons of the spool flonge (ll) on to the toke-up
           spool. See fig. 3.
 s     9. Fully push in the dork slide (10) until it clicks in.

10. Set the film type ond the film speed on the two indicoior discs (2).
      With q film looded into the interchqngeoble bock, the dqrk slide must only be wirh-
     drqwn when inlerchongeoble bqck is qttqched lo the comerq. Even the slightest
      withdrowol of the dork slide will fog the film underneoth. The interchongeoble bock
      con only be ottoched to the comero, or removed, when the comero shutter is tensioned.
         ll. Attaching the Interchangeahle Back
       1. Remove the comero bock, toke out the pfostic insert ond the toke-up spool, ond
         store them. These items hove to be reploced for looding o film ogoin without the
         interchongeoble bock. See fig.4. Toke core thot the plostic insert is fully pushed
l0      home with o click.

2. Tension the comero shutter. Attoch the interchongeoble bock io ihe comero in the
  some woy os the cqmero bock, ond close the boseboord locking keys (.|3, l5). lf the
   interchqngeoble bqck cqnnot be fitted stroight qwqy, slightly turn the rewind knob of
   the cqmerq. On locking the interchongeoble bock to the comero, the toke-up chomber
   closes.
3. Depress the cotch (3) ond fully pull out the dork slide (10). Keep the dork slide in the
   retoining ledges  ('l). See fig. 5.
4. Moke two blind exposures, ond then turn the frome counter (14) in the bose of the
   interchongeoble bock with your finger to No. 36 or No. 20. The comero is now reody
  for shooting. The frqme counler mechqnism olwoys indicqtes the nurnber of unex-
  posed film frqmes still qvoilsble

5. When you corry the comero in the ever-reody cose with the interchongeoble bock in
   ploce, the frome counter is visible through o hole in the bottom of the cose.
lll. Remouing the Interchangeable Baclr
l. Tension the comero shutter.
2. Fvlly push in the dork slide (.l0) until it clicks in.
3. Open both boseboord locking keys (13, l5) of the interchongeoble bock, ond pull the
   lotter off the comero. Keep the interchongeoble bock in o suitoble contoiner until
   required ogoin.
4. Attoch the new interchongeoble bock os described obove, with the comero shutter
   tensioned.

5. After ottoching the interchongeoble bock to the comero, the shutter con be releosed
  once occidentolly without pulling out the dork slide. In this cose one film frome
                                                                                         the  remoins unexposed. The dqrk slide (10) must however be removed to recock
  comerq shutter. Ensure thot the dork slide is olwoys pressed home - or withdrown -
   in o perfectly stroight monner.
lU. Bewinding the Film
l. The exposed film is rewound into its cossette inside the interchongeoble bock with
   the lotter on the comero. The rewind cronk of the comero serves for rewinding. The
   dork slide (.|0) must be pushed in during this operotion.
2. lf the fllm wos rewound without the comero being tensioned, the interchongeoble
