Frank Filippone red735i@earthlink.net Frank, I think you're making the assumption (as I have) that "APO" and "apochromatic" are interchangable and mean exactly the same thing. In this case "APO" is a marketing designation, like "ED" is for Nikon lenses. It looks like it's an abbreviation for "apochromatic" and the "APO" terminology was probably chosen to make us think that, but I think we'll all comprehend this better if we think of "APO" as Leica's way of saying "ED".
