Re: [Rollei] Right back for 220 TLR?

[Dirk-Roger Schmitt <Dirk-Roger.Schmitt]

Of course,

the depth of the film channel for 35 mm and 120 mm film is different. 
Rollei themself specifiy different values, which I don't have in mind. 
However, I remember  that Bob reported some time ago about the depth for 35 
mm. This value - I did doublecheck that - is still valid.

Also, the depth of the film channel is different for the 120 am 220 film 
magzines for the 6800 series, of course. Otherwise it would not be necssary 
to have different backs.

However, I don't know how it was handled for the TLRs. I shall check my 
2,8F and let you know the findings. Bu I am very sure to find that the 
plate will move in lens direction in the 35 mm position.
