The colour of the coatings are also different, but performance is about the same. I can't see a difference.

    I have a long nose AI Nikkor
    an early all black poly carbonate E
    a late aluminium E
    and a pancake AI-S Nikkor

    the last three are only different in few grams and rabbits ears.
    The coating colours are different in each but all are vestigial reflections as multi coated things should be not vibrant single colours like my single coated lenses from pre 65.
    I've only got one to hand to check as Im away from home.

    Thanks Noel!
    As a curiosity, some marketing photos of lenses are manipulated to exaggerate the coatings colour. I saw this on Flickr and it made me laugh: http://www.flickr.com/photos/8678824...-bfUMFe-9jUrra

    thanks for all the suggestions, but thanks to Ken Rockwell's amazing site, I finally figured it out.It has nothong to do with quality ,manufacturing lines or inspectors.It is simply a recycling code.Sadly Nikon is assuming that their product will eventually ends up in the trash and at a material recycler.

    And what do they mean??

    So far such coding has only be employed to one-material parts. A whole lens though is a conglomerate of materials.
