I have not yet tested the Elmar 1:3.5/65 since I do not own a visoflex. Perhaps it's easiest (and cheapest) to buy a micro four thirds and an adapter? By the way, it's from 1964 according to the serial number while the M3 (single stroke) is from 1958 (my year of birth) and the double range Summicron 1:2/50 is from 1962.
