  3. Photavit camera shutter releases works only when film is loaded and one frame advanced.

    First clock the Compur shutter

    Next turn the film advance knob unti it stop, one frame advanced, the shutter release can be pressed down to activate shutter

    At other time, the shutter release wont bulge.

    Photavit take up cassette is very rare.

    The Photavit cassette maximum capacity = 25 exposure of 24x24

    The Photoavit camera counter max count=25

    Film length is about 30x 25 = 75cm

    This is about 20 exp 35mm film

  5. Regular 135 film cassette wont fit to the supply side of Photavit camera, film must be transferered
    tor Photavit cassette for use in this camera.

    top speed 1/200 only vs Compur Rapid shutter 1/500

    8 sec delay timer
    The film advance knob is substantially different than the Photavit with Compur shutter.

    This version, after each shot, the rewind knob must be PULL UP AND TURN, otherwise the knob
    refuse to bulge.

    This version Photavit has no sprocket drive, hence can use both perforated or unperforated 35mm film.
    However, paperbacking is not necessary, the double exposure prevention is built into the film advance
    knob, only after the shutter is released, the knob can be turned.

    The Compur Photavit has no such problem

    Photavit camera is smaller than Rollei 35s
     
  10. Operation procedure for Photavit with Pronto shutter

    1) Film loading.
    Open camera back by pull up a spin at the left had sidde, then lift off the entire back
    Take out the two cassettes, if anu
    2) Use Photavit film loader
    Open one cassette by lift off the end cap, take up the spool, take a new 35mm film cassette, cut a film tongue
    about 1.5 inch long, insert into the wide slot of the spool, push the film tongue throught the thin end of the
    slot, pull it another inch, than wrap it around insert the free end into the wide end of the slot again, pull
    the fillm tongue such that the film wrap arround the spool tightly, insert the film back into the cassette
    close the cap, tape the top with a piece of Scotch tape to prevent it accidentaly comes loose.

    put the Photavit cassette and 35mm film cassette into the Photavit film loader, put back the photovit
    loader top cap , turn the winding knob until cannot be turn again, the film is fully loaded. Open the film
    loader, cut the film,
    Pull out 2 inch film, cut a narrow tongue, and insert it into the take up spool of another Photavit cassette
    wrap the tongue around and insert the free end back into the wide end of the slot, pull tight .Put back
    the top cap, make sure it fits tight and not slanted, otherwise it is difficult to put the cassette into the camera and even more difficult to take it out.

    To put the cassette into the take up side of the camera chamber, pull the top part of the knob all the way
    out, do not pull the whole knob up, other wise, the cassette cannot fit in.
    put the other cassette into the right side chamber. wind the film winding knob to tighten the film.
    Close the camera backl

    To reset the counter to zero: pull the top part of the winding knob up, turn the lower part of the
    knob such that 0 aligned with the index dot mark.

    Take picture
    Hold the winding knob top part and bottom part at the same time, pull it up turn clockwise a little such
    that the retening pin clear the hurdle, the release the knob to let it falls back, turn clockwise until stop
    clock the shutter. The camera is ready for first picture.

    Go to next frame, do the same with winding knob pull up and turn to clear hurdle etc etc

    Photavit cassette vs regular 35mm film cassette
     
  12. Photavit leather case

    There are no eyelets on the camera, so you cannot carry the camera with a strap, the camera is quite
    solid and to heavy to put into pocket. You must carry Photavit with Photavit camera case

    Photavit camera case usually comes in brown leather.

    Some case is sold separately

  13. Photavit cassette is all metal,(metal shell and metal spool), it is thinner than regular
    35mm cassette, but lthicker than Tessina cassette. In short it is in between
    regular 35mm cassette andd Tessina cassetter

    Use Photavit film loader to load film from 35mm cassettte to Photavit cassette.

    One 35mm 36 exp film yields about two rolls of Photavit film , each about 25

    exposure 24x24format.

    A complete Photavit boxed camera contains

    1 Photavit camera
    1 close up lens
    1 lens cap
    1 Photavit film loade
    several Photavit cassettes.

    Photavit cassette is much harder to find then Photavit camera it self.

    You need a pair of Photavit cassettes, on for film supply, one for take up

    It may be possible to use Photavit with only a take up spool, for that you
    must load film in total darkness, by roll up film and put in the the take up chamber
    cut a tongue and insert iit into the take up spool slit

    The spool has a see thru slit, one side wide the other side narrow. Insert the
    film tongue thru the wide slit out from the narrow slit, wrap the film around
    and loop it back into the thick slit, close the cassette cap and tape with a piece of
    Scotch tape
