    I am kind of doing a survey a "Show Of Hands" so to speak about those who would like an instant film holder like a Polaroid 405 for their Graflex, Linhof and other rangefinder 3 1/4" X 4 1/4" format cameras, even the few models of view cameras in that format.

    I am going to post a "WillItFit" tutuorial guide to take away the mysteries of whether or not this new type of holder will work on your particular camera.

    I am hoping to produce just one version that will fit a lot of cameras without one needing to cut or modify the holder or the camera but may also produce ones for certain rare cameras as well.

    This new type of instant film holder for the Fuji Pack films I am going to call the Polaroid 304 holder.

    Research is under way and drawings being made for my machinist to produce a proper interface plate to be fitted to the Polaroid CB-103 holder.

    If interested, I need photos of your particular 3x4 format camera's rear opening plate with the ground glass spring back removed.

    At this time the new Polaroid 304 film holder does not look like it will be "Graflockable", will need to be slipped under the spring back or other method of holding it in place.

    Would like to get $175 each for these backs if indeed I see enough interest in this new product idea.

    I would love love to have one of these that could fit a 3x4 RB Graflex- I have been trying to figure that out on my own for a while, but have not gotten very far.

    Y E S !

    to make sure it easily fits any camera, you may consider a 2-part design--one with a darkslide that holds the film pack for exposure--like an old 3x4 filmpack holder. You shoot, replace the darkslide, take out the holder/filmpack and attach a roller attachment to pull the film through for processing.

    existing 3x4 filmpack holders look like they can be very easily modified to this design perhaps.

    ALSO--VERY VERY interested in fuji INSTAX wide filmpack holder or holder/external roller processor as above.

    I have made Polaroid 110B and 900 cameras with a Polaroid Spectra back, uses the new Impossible film.

    I have been looking into Instax, first project is perhaps an Agfa Isolette 6x6 folder with Instax Mini back on it.

    A Polaroid 900 or 110B is possible for Instax wide, I would need to buy and cut up an Instax wide camera and crack the circuit code to make it function, to be honest cameras like these with the exception of the Isolette project start at over a grand.

    Both a 110B and a 900 with 150mm F 5.6 Fujinon lenses sold for $2500

    I've had a crazy idea of seeing whether an old Kodak "The Handle" camera I inherited could by adapted to use Instax film.

    the problem with polaroid/impossible integral film is that the image is inverted whereas the instax image would be normal. I have a polaroid cb70 back for my mamiya universal. there are quite some universal and polaroid 600SE owners out there who would want an instax back. it is a constant subject of discussions on polaroid passion. until now nobody was able to hack the instax circuit. no need for complicated work on camera conversions, a back would do. you could ask the future clients to send in a frame and a functioning instax wide.

    Yes, if your design would fit a 3x4 Graflex SLR.

    it seems feasable to somehow convert all the unused polaroid sheet film holders to processors for both fuji instax and pack film.

    SEEMS feasable.

    Well....You know.....I am thinking of buying a broken 3 1/4" X 4 1/4" double dark film holder that is broken on ebay for 8 bucks for research.

    Somehow at this time I don't see much point in investing 8 bucks for this broken film holder to use for research to produce the "304" film back.

    Perhaps you folks on this forum could show a bit more enthusiasm toward a project like this???

    I have just finished one. I used the base plate from a film pack back, drilling out the pins that held the plate to the box that was meant to house the film pack. Adding a 3/16 thick frame of wood to the base, I could then glue on the Polaroid back from some version of the M4 or M3 copy cameras that were being thrown away all over the place a few years ago. Pretty good fit but I had some problems with light leaks. All solved now, I think. I went through a full pack of film testing it, though. So much for wild-ass guessing instead of careful craftsmanship.... Ah well, if you're going to be dumb you gotta be tough. I took the loss and moved on.

    Focusing on a ground glass placed in the film holder allowed me to shim up the GG until that was also in focus. Not surprisingly, it needed just over 3/16th of additional distance from the mirror.

    Now to go out and actually use the thing.

    New findings, anyone?

    I have an old Zeiss Ikon 3 1/4" X 4 1/4" pack film holder, rather sure it is of the 3 1/4" X 4 1/4" format, it measures exactly 3 15/16" wide, is that the correct width for this format's film holders?

    The actual Polaroid CB-103 plastic pack film holder is wider than the old Zeiss Ikon film holder I have, it is 4 1/4" wide.

    The proposed 304 holder looks to be one that will never slip under the ground glass spring back but be "grafloked" on to the camera.

    One measurement that would really be good to have is the actual depth from the camera's back surface to where the film sits, could it be the same depth as a normal 4x5 film holder? this depth is easily sorted out by measuring a 3 1/4 X 4 1/4 double dark sheet film holder, measure from the face to the film plane, that is the depth measurement I need for now, hopefully the Polaroid Cb-103 being 4 1/4" wide it will still clear and be set back far enough to clear the grafloking tabs and mechanism to fit and such that the grafloking tabs can hold the 304 in place securely.

    I am thinking of buying a 3 1/4 X 4 1/4 double dark sheet film holder off ebay for research.

    Some how this project looks like the 304 holder may have to be made on a "Case by Case" basis if the concept will work at all, locating and using a darkslide could be problematical in that one may not be able to insert the darkslide in and out while the 304 is on the camera.

    let me know what you think.
