Hello, after a while I am going to start a question here. Can you help me out with some questions about the flange focal distance of Rollei QBM? First, on a couple of websites the number of 44,70 mm is published. Also on Wikipedia this value was published. http://de.wikipedia.org/wiki/Auflagemaß In the meantime, this value was corrected to 44,50 mm, and it is mentioned that the 44,70 mm was published erroneously. So, is there anybody who can confirm the 44,50 mm? Thanks a lot and best regards Dirk Dirk-Roger Schmitt
