I wonder if somebody with a Fujinon 90 f8 (newer outer lettering) could do a couple of measurements for me. I would like to know the depth the rear element sits behind the flange and the diameter of the rear element.
Also if your a great person the film to flange distance at 24m and 1.5m. I know that might require some setting up so only if your keen to help. Nearest mm is fine.
