It is not the first time I mention this in the list, but I had the Sigma 70-200 2.8 HSM in Nikon AF mount until last week (sold it to a guy who uses a Nikon D300), and focusing isn't any faster than my FA* 80-200 2.8 used on a MZ-S. It is almost completely silent, though, and it is the main (and possibly only) advantage of Sigma HSM lenses over the screwdriver AF ones.
