Hello everyone. I have posted before about this, but I am comming closer to a decision. I am in Lust of a 80 to 200 or 70 to 200 2.8 lens. The Nikon VR is just plain out of my price range. I have read alot that the Tamron has very slow autofocus. So that is pretty much ruled out. I am now faced with the sigma and the used nikon versions. I know I want a D version since i do use flash often also. I see Sigma has their version II now. Does anyone know the difference from the prev version. The other is does anyone have any comparasions between the older nikon push pull's and the AFD 2 ring vs the sigma. Thanks for your help.
