I see my usual shop is full of 135, 120, 220, 4x5", 6x9", 8x10" and other formats(the ones in inches are sheet, not roll, though), but not 122.
I figure that a 6x9 or 6x12 cm negative is large enough for me when messing with pinhole photography. (Using a Holga 120W camera)
I have a Lubitel that also uses 120, but in 4.5x6 or 6x6cm format, a couple of Olympus OM bodies(Anyone havee a 4ti needing a loving home? I'll pay for shipping , and a Zenit Horizon 202 for when I want to really waste film. (Taking good pictures with it is very difficult.)
I really want a 203, but I really can't spend that much on a camera, even if doing 120degree panoramas on 120 film would be neat.(12x6cm negatives. = 6 pictures on ech roll... )
Working(now and then) on fixing an old 70s Zenit-E that I got cheaply on an internet auction. (It came with a 500mm F:8 lens... It's long... very long... )
