Buying the ready to roll Polaroid back for the Holga seemed disproportionately costly to a friend. I agreed and ran a Super Shooter or similar thru a band saw & amputated the Polaroid back.
After a few attempts to visualize how it could possibly be made to mount at the proper focal plane for the existing precision optical lens :O), I concluded
either I hacked the wrong model of camera or Polaroid actually made a custom back for the Holga...kind of hard to believe, but that would explain the cost.
I then rationalized that we could possibly do it for macro work with a new implied working focal range. Then I decided next time the shutter craps out, PINHolgaroid would be the easiest solution to this headache, as the focal length/image distance would be less critical and a pinhole could be selected afterward to match.
Has anyone looked at the Holgaroid back closely enough to tell if it's custom for Holga or do I need to fire up the bandsaw again and visit another flea market?
Incidentally, the bandsaw worked much better than the last one I did with a Dremel cutoff wheel (right tool for the job makes things easier, eh?)
The one I have is designed for Holgas. Mine takes type 87 and 89 film (the older stuff). I think Freestyle sells a newer version that uses a newer version of film.
For anyone who cares...
I removed the lens/shutter ass'y from a Holga 120N, and measured the front-back depth for spacing the lens from the amputated Polaroid camera back.
I measured 1.272" in a couple places (back may not be flat, and there is no pressure plate...I probably have to review this & alter it later after I decide where the film in a Polaroid pack would actually be.
