I completely agree about variation among film holders, been there done that. Fasteners are about the most standardized things we have, but if you measure enough of them critically, you will find that they are all over the place. I MAY make film holders to fit cameras I produce, but I am never going to produce film holders for other cameras. The slight variations would make me pull out what little hair I have left.Originally Posted by sanking
