The "Hi-Speed" of the Maxxum 80-200mm f/2.8 G isn't any special
technology. It's just a re-geared version of their original lens. The
Maxxum 7 cranks it into focus fast. I would imagine a USM or SW motor
would be slightly faster. The best thing about those is they're quiet. I
never noticed that the Maxxum 7 made noise until I heard (or didn't hear)
USM. Picture taking with an SLR is never going to be quiet, so it's not
that big a deal. What do you (original poster) want to shoot?
