I've come across some of the above mentioned type 85 and also 89 pack film and would like to use it-the only problem is I don't have a square shooter or any other compatible camera or back.I've got a polaroid back for my RZ this of course is for 31/4 x 41/4 and works fine.Does anyone know of a way to get the type 85 to work in my larger back?Thanks for any suggestions,Al.
