Had a play with all 3 lenses yesterday in BH Photo over in NYC as I am keen to pick up one of these beasties soonish!
The Nikon is clearly the winner (and it should be for the price) it is now $1900 over here and TBH it really doesnt feel like it is worth over twice the price of the other two!
The Tamron really did seem to have the slow AF issue apparant even with my short time playing with it, it also spent ages hunting when used within the shop (and the lights were pretty bright) so that was scratched off my list straight away!
Interestingly though (and I know I couldn't compare actual IQ in store (at least only on the LCD screen of the D300 I was using) the Sigma was top dog in my opinion, the AF was pretty quick, very little hunting and kept focus pretty well on some poor souls I tracked round the store!!!! In addition it felt the lightest and most well balanced of the three (even against the Nikon, prob because of the extra weight from the VR) and this was with the collar on which obviously if you werent using on a tripod you could remove to save even more weight!
Anyway wanted to post my thoughts as I know there have been a few threads on here about this range of lens.
Now just go to decide if I want to splash the cash on the Sigma
