Number of exposures per roll of fill

I'm responding to an answer sent me privately by Rick Campbell. First,

Thanks to Rick for his response. I'm replying here because it brought

up two questions I'd like answers from the MFD in general.

Rick responded to the circles of light I commented on earlier in

photos using 220 film in my Kiev 88. Actually, I'd figured out what

caused them and was pointing out using 220 in that back isn't such a

good idea since it relies on the backing paper for good light leak

protection. Rick stated early Hasselblads used a rubber cork in the

light tunnel to prevent the problem. I'd wondered about doing something

like that, and now it seems like it might be a good idea. Has anyone

tried it and does it work?

Secondly, in an earlier post I'd repeated what I'd read somewhere

(can't locate the source) that most Japanese made medium format cameras

limit you to 10 shots vs. 12 on 120 and 20 vs. 24 on 220. His answer

implied that is not the case. If this is a misunderstanding on my part,

it could certainly influence future buying decisions. Would those of

you who use Japanese made cameras, especially with 6x6 negatives, comment

on this? Are there some with artificial limits along these lines, others

without?

Thanks in advance! And thanks again to Rick for his note to me.

The rubber cork does work on the kiev 88. I have used it extensively

even though I did not have a problem with light leaks with 120 film.

(I haven't run 220 through the camera yet). I have also used the

stopper on the Hasselblad M-12 magazine which has a similar problem.

The rubber stopper are not hard to find but it is best to find just

the right size to fit inside hole and still allow to close the cover.

Good luck,

My Mamiya TLR gets 12 exposures on 120, and 24 on 220. My understanding is that Japanese 645 cameras get 15 exposures per roll of 120, while and other makers' cameras get 16.
