I've read the 2003 thread about spacing overlap in old Rollex backs, and the consensus there was that the problem is due to thinner film base and backing paper these days compared with earlier films.
I have just put a roll of film through a newly acquired Linhof 6x9 which has an older knob-wind Rollex back, and found the expected frame overlap - more at first, less toward the end of the film. There can be no possibility of wear in this case as the back (and camera) have had very little use. The problem is no doubt due to today's thinner films.
I have seen a different thread on this forum in which there was discussion about adjustment being possible to these backs. Of course, now that I want to follow up the thread, I can't find it - Murphy's [or someone's] Law!
I'm keen to fix the problem once and for all, as I'm not sure that giving an extra 'tweek' to the knob at each frame is a workable solution. Does anyone know of any adjustment that is possible for these backs?
Many thanks,
Baz.
(BTW film turned out great - Efke and PMK, beautiful!)
