I'm looking into getting a new telephoto and I'm pretty sure I'm gonna go with this one, but I can't find much in the way of an extensive review. Our good friend Ken Rockwell sings it's praises, but he also admits to not using it much(http://www.kenrockwell.com/nikon/80200.htm). I know most people will say save for the 70-200 VR, but it's out of my price range right now, plus I've been shooting low light for years without vr and I can hand-hold down to 1/4 without a problem already, so it seems a waste of money right now. And I don't mind paying 150 bucks more for the older nikon than the newer sigma 70-200. Has anyone here done much with this lens?
