The old one had lousy handling, terrible optical performance from 300mm to 400mm wide open with the IS activated, and the IS was just this side of useless.While I strongly disagree on the first point (I really like push-pull zoom) and wouldn't use anywhere near as strong words on the others either (having taken thousands of pictures with it and been happy with the results), I would definitely like better optics and IS and while the extra weight worries me (as I'd be hiking with it in the wilderness), I probably will upgrade mine if the new one is good enough. I'll wait for reviews first, though.
I like the push pull too. That wasn't the lousy handling part.
I use mine wide open at 400mm all the time and it takes sharp shots. The IS is a little weak I will agree.
