This would cause uneven film advancement, It would also spawn a whole new business. Exchanging flat pinch rollers. The second problem is that Leica would have to make their own film. Not likely! I suggest instead, you buy a Hassy, Rollei, or 6x7 Pentax for that larger, no sprocket hole, film format. Jim
