I am looking to do some projects which will require a 35mm roll film holder on my 4x5 camera. I cannot find one anywhere. A google search doesn't pull much up either. I often do cross format film tests and require the film plane to match the ground glass, so a simple t-mount for a 35mm camera won't do. I see there are 35mm film holders for some medium format cameras, but I can't seem to find plain graflok plates for the brands that offer the holder. Anyone know of anything I could use or adapt before looking at having something made?
