Ben's list (admittedly wrong as there were no M series list before 1953) lists this number as 1943 - any thoughts? When did Leitz change to the modern f/2-2.8-4-5.6-8 etc. rather than the F/3.5-4.5,6.3,9,12.5 stops and are they what we consider "half stops or are they translatable into the modern system? Sorry for the elementary question but am away from my home library for most of the summer. Regards, Doug
