So I know I can use my Polaroid 545i Back with Fuji Quickoads, can I use my Kodak Readyload Back with Fuji Quickloads too? Or is it destined for the classified ads?
You could consider the Kodak Readyload holder as a back-up for a Fuji Quickload holder. The trouble is that if you get the film inserted reversed, or try to be too quick with it, then it will jamb. Once it jambs, then you need to disassemble the holder. Outside of that, once the supply of Readyload films is used up in a few years, there will be no further use of it.
