One reason I wasn't looking at the 100-300 was because it's a push pull zoom. Personally I'm not a big fan of lenses like that and I prefer the more modern design "2-touch" zoom lenses. (thus - my interest in the 85-300)
Actually The first zoom lenses were two touch, its the push pull type that are the more recant.
