Oh I see.

I was thinking if I could get a 21mm (for 35mm film) and then just mark where the 6x7 vertical edges were at least I would have some better idea of what the image would be, but the only thing out there for that are the Leica viewfinders which are also like $300 a piece... It is really frustrating....
