I just got a brand spanking new old lens. It is German with European markings. I checked the back files here because this is probably a simple question, but I c ouldn't see it. The dial representation is arithmetic even though the stops are logarithmic, so does that mean that I just mark of where the modern #'s are and it will work? Simpler, it goes 4.5,6.3,9,12.5,18,25,36, so if I just make a strip of paper the same length as the bezel will it be accurate? Simpler-- how do I convert old f-stops to new f-stops? (My meter don't speak the old dialect). Dean
