Hi,
I just bought used SUMMICRON-M 50/2 serial number 395xxxx.
I have a few questions please-
1. The focus ring goes little bit beyond 0.7 (to the left- like towords 0.6) is it normal?
2. when the aperture ring is on 2 or 16 it can turn a bit more of a click and change the aperture – little bit open from 2 or little bit close from 16 (at 16 spot you can't get perfect round aperture like at 16.1. And lets says the aperture goes beyond 2 to 1.97 and beyond 16 to 16.1)
is it normal also? if I want to use aperture 2 or 16 how should I aim my aperture- to spot 2 or 16 or little bit beyond?


Many Thanks!
