Re: Angenieux Retrofocus R1 F.35/1:2,5 Leica m mount

ph: I appreciate your comment. It seems that retrofocus series was very new by then (year 51/52). I am trying to understand what you wrote: Is that there were no wide-angle lenses for 35 mm photography before ?

box86rowh: I truly appreciate your interest. I am evaluating it. But I can not begin to negotiate right now because my inquiry to this community was motivated in the context of another negotiation.

Re: Angenieux Retrofocus R1 F.35/1:2,5 Leica m mount

You are right. It is a adapter! Good catch! In the contacting side of the ring has the legend " Leitz Wetzlar Germany DBP" and "M2 21-35" and "M3 135". The screw mount seems to be 39 mm (see the pictures).
