John, I wondered about the F 70-210 f4~5.6 long ago when folks claimed it had an undocumented aspherical element. When I finally got one, I was pleased with the results. I think the lens is better than the FA 80-200 f4-5.6 power zoom (the wobbly one). The M 200mm f2.5 is a virtualy unknown lens, but a nice one. Somebody should buy yours! (I don't need a second.) Regards, Bob S.
