    Can anyone tell me what kind of coating reflections a (80mm) Componon S is suppose to have. I purchased one used and compared to my Nikons it looks like it is un-coated.

    At first glance, the reflections in my 135mm Componon-S appeared white. Upon closer inspection, however, at least one set has a subtle pink tone, as do a couple of earlier Componon models in my DR. This is a big difference to the bright magenta reflections in the 40mm APO HM I have.

    When I looked at it closely it appears faintly gold or warm lets say. A bog difference between this and the Nikon which is heavily coated. Were there single and double coated versions of the Componon S lenses?

    I'm not at all sure, Wayne. Looking at the Schneider site, the Componon-S description says nothing about coating, while the APO-Componon HM page specifically mentions multi-coating. Perhaps the Componon-S isn't coated at all, and the slight pink or gold color we're seeing is just attenuation from the glass.

    I'm going to compare the two brands I have and see if there is any difference.

    Any difference between the Componon-s and the Nikons?

    Wayne, just quirous to hear if you find the Schneider Componon - S performance superior to the Nikon's?
    I'm contemplating buying the same lens to replace a Nikon.
    Thanks.

    Of the three major enlarging lenses I have found the Rodenstock Rodagons to be the best.

    Look forward to hear about your results Wayne.

    As for the Rodenstock Rodagon, are there any difference except for speed between the 4.0 and the 5.6?
