Emanuel,

yes, but  what is correct?

44,50; 44,60; or 44,70 ?

The link of Wikipedia I was including was saying, only some months ago: 44,70 
mm.
Now they mentioned there was an error and corrected to 44,50.

I will doublecheck with someone from Rollei again, but any matured data someone 
has in a service manual will help.
Reason for my inquiry is  that I have problems with fitting my Zeiss lenses 
with QBM to a Canon support. The adapter seems to be manufactured too thick.

Best regards

Dirk

Hallo Dirk-Roger !

According to the various compilations available on the 'net [available does not 
means realiable :  44.6 mm is mentioned for the QBM ...], the figure of 44,7 mm 
seems to be the flange focal distance of the Voigtländer Bessamatic.
