Hi,
The subject is a Summaron 35 3.5, and its serial number is 1283815.
Looks like it's from 1955, from an M3 use batch. I understood -until now- some Summarons 35 3.5 were made in screwmount, and some in M-mount with spectacles (gogles), being the later made for M3 use, precisely those to be aware of if the plan is using them on other bodies than M3 because they're unable to focus properly when separated from gogles...
Well, I just read on the net some M3 use Summarons were possibly made without spectacles, and some of them were even screwmount, so now I got totally lost because I don't understand the reasons... Can anybody explain, please? Surely I'm wrongly assuming part of the story...
Is it possible that this serial number, even belonging to an M3 use batch, is from a lens that a) is screwmount, b) never had gogles, and c) can focus properly on all M bodies?
Thanks!
