I can understand why someone might not like the ASPH correction in a lens; I *think* it is residual spherical aberation which is the basis for lovely "bokeh" which people get soft and fuzzy over (or conversely might be the cause of "brittleness"), and which is highly corrected in aspherical designs. APO design merely reduces chromatic aberation, which I can't see having an unintended detrimental effect on a len's performance. -dan c. At 07:48 AM 03-11-04 -0500, William G.
