[Leica] OT: RZ67: 220 film in a 120 back?

[geordiepete211 at yahoo.co.uk (Peter Cheyne)]

Thanks, John,

yes, I gathered that the only differences in the holders would be that  
the 220 holder pressure plate would push out a fraction more.  The  
backing paper thickness more, as you said. And secondly, that the  
counter would read differently.  But I don't think the frame counter  
matters; I'd just remember that I have more shots left.

I just wanted to hear if the difference in pressure plate extension  
matters critically for focus or film flatness.  Also, if it really  
does, is there a way around it for one day, such as taping paper to  
the pressure plate?

Peter

It will be the thickness of backing paper further back from the focal  
plane,
also does the RZ stop single stroke wind-on after 10 frames? Fogging  
would
be the other issue but the RZ is probably fine....

I'm going to a waterfall with a friend tomorrow.  I'm taking an M7  
with TMAX
for the walk, and wanted to take the RZ67 with Velvia 100 for the  
falls. I
just got my RZ out to get ready for tomorrow, and realized that it has  
a 120
back, but I only have 220 film. Would there likely be a film flatness/  
focal
plane problem if I used 120 film in the 220 back? Has anyone tried it?  
We'll
be leaving in the morning to pick up my buddy, and there's not much  
chance
of picking up some 120.

All the best,

Peter
