Mamiya RZ67 220 6x7 back and 120 film question
Hi there,
I am using a friend's Mamiya RZ67 camera. It has a 220 film back with it (6x7 format). I see on the Mamiya website that there is a 6x6 format back that is listed as possible to use 120 or 220 film. Does anyone know why 120 film can't be used in the 220 (6x7) back? Has anyone tried it and had success? Is there a modification of any kind that can be done? Len "with a bunch of 120 film" Bryan |

Len "with a bunch of 120 film" Bryan The concern with running 120 thru a 220 back is that with the paper 120 is thicker and *may* place a strain on the back's winding mechanism. |

That makes sense. I may try it out with an old roll of film I have. If it feels like it is straining, I won't do it again. Thanks, No reason to use old film. The real danger is to the film back on your *borrowed* camera. I'd ask the friend before running the film through the camera. Even if he/she says yes, if the winding feels tough, abandon it and toss the film since there is no way to rewind or wind to the end without risking further damage. You may also find the pictures aren't as sharp since the film may be in the wrong plane - I've never really stopped to think what determines the location of the film plane in the RB/RZ backs. I've asked about it and he is O.K. with the test. However, the more I think about it, it's not worth it to me. I do have a 120 (6x4.5) back for it and can use the 120 film with that. I'll just have to go buy some 220 rolls for 6x7. I agree that it isn't worth the risk to the camera back. I would be mortified to damage his camera. Also, I didn't consider the potential focus issue. Using 220 film will certainly reduce the time spent loading film. 8-] (I'm not smooth with this camera yet) It seems that there is "slightly" more variety in films for 220 vs. 120. That is likely only a store level stock issue though. Thanks, Len Bryan |

I _seem_ to be getting no more funky soft areas with my 35mm lens on my Mamiya 645 since I switched to 220. It seems that there is "slightly" more variety in films for 220 vs. 120. That is likely only a store level stock issue though. Actually, I think it's the other way around: there are quite a few films (e.g. XP2) that aren't available in 220. Of course, XP2 is so gross and grody that you'd never notice film flatness problems... David J. Littleboy Tokyo, Japan |

Of course, for some situations or aesthetics, that may not be a win. As to the frequency of loading, you'll get 16 exposures from 120 in the 4.5x6 back vs 20 using 220 in the 6x7 back. While you're still learning, the extra economy of the smaller neg might be a win. It seems that there is "slightly" more variety in films for 220 vs. 120. That is likely only a store level stock issue though. I think this is strictly a local phenomenon. If you look at what is available from a big supplier, like B&H, you'll find far more variety in 120. Of course if your favorite film is available in 220, it doesn't matter how many aren't. |
