I've searched around a bit and can't find what I'm looking for, so I'm going to ask here. I know it's a weird question, but humor me.
Most of us know about roll film adapters - let's you shoot 6x7, 6x9, 6x12, etc. on a 4x5 or larger camera. Has anyone ever made a roll film adapter for larger film - so you could shoot 4x5 or 5x7 on roll film? If not, why not? Why would that not work (assuming you could get the film)?
Roll film just seems like it might answer some of the weight and dust issues that we get with film holders.
