The AF is considerably faster (with limiter) and side by side the 100 is as sharp or sharper, if that is a concern.

You think a significant difference in sharpness at f/3.5? Wish I'd had time to do a side-by-side test. Regardless, sharpness isn't really an enemy with my work. I could see it being a possible issue for some glamour portraiture, but not for my commercial headshots.

I remember the 100 being slightly sharper in corners. It was my overall impression from various types of shots. Here is a side by side test (approx. 300ft, actual pixels from 5D2) where it might be even the other way around.

I had the 100 only shortly, but it was my impression that it is more resistant to veiling glare.

Help a dummy out?

I got some shots with the 85 where sun caused veiling flare over the whole frame or part of it. The 100 seemed more resistant to it.
