    "Of the 23 elements in seven moving groups, seven are made from glasses with anomalous partial dispersion for the minimisation of chromatic aberrations. "

    I looked it up. It's just another way of saying "Low-Dispersion" as compared with standard glass. Like Thoriated glass.

    From Nikon:
    "This characteristic is known either as "extraordinary partial dispersion" or "anomalous dispersion" (in this article, the term "anomalous dispersion" will be used). Nikon has dubbed glass that possesses this characteristic "ED glass."

    Brian, I guess now a days, "ED" is just not as sexy anymore. :laugh1:

    I keep wondering why all the ads to cure ED, I mean ED cures chromatic dispersion, right....

    Nikon never was good at picking trade names for gear. Nikon Ftn Photomic or Nikon F Tn Photomic? Could use that to get across a troll bridge.

    I'm guessing that would be a birder's dream lens.
