    Is Mamiya 120mm Macro APO?

    Keep seeing references to the 120/4 as being 'APO'. While Mamiya indicates it's ED glass delivers APO-like performance, does it actually ahve APO elements per se?

    No, it's an achromat. But achromats can be designed to use anomalous dispersion glass just as well.
