    What is the differnce Rodenstock lenses

    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.

    The colored rings are a marketing gimmick.
    Rodenstock added them after Schneider started using them.

    AFAIK, there is no difference in vintages of Rodenstock lenses.
    The re-designs changed the lens series name, e.g. going from Apo-Sironar-N to Apo-Sironar-S.

    Not exactly - the coating changed from the N - S -- The S has better contrast.

    The -N and -S are different designs.
    For example...
    the IC for the Apo-Sironar N 210/5.6 is 301mm, while
    the IC for the Apo-Sironar S 210/5.6 is 316mm.

    I'm sure each lens used the best coatings available at the time of manufacture, but I doubt that's the reason for changing the letter.

    My poorly-phrased point about vintages is that I'm unaware of major changes occurring that were not accompanied by a name change.
