Hello,
Could you please help me identify this lens? The wiki on this site indicates a summicron v1:
2307451 2307750 Summicron 3.5 cm 1:2 (M-black.ELW) 1968 300
But, the shape of the lens and an expert's advice make me think that this lens bears the new design (id est version II) which could have started at number 2307451. In that case, the wiki would be erroneous.
I am totally unable to say wether this lens has 8 elements or 6 elements.
Thank you.
Olivier
