Hi,
what is the difference between a rodenstock lens with a coloured ring at the lens Barrel (like green, silver, ...) and a lensbarrel with no ring.
For example:
a) Rodenstock Sironar N 180mm /5.6 with no ring
b) Rodenstock Sironar N 180mm /5.6 with a silver ring
Are there any technical differences? Quality? Age? Better or worse one of them? A "NoGO" for digital...
Thank you.
