I'm in a similar dilema, I am thinking of the Tamron 70-200 2.8. I've decided to stay put with the Nikon for now.. I think anyway!
The Tammy appears to be a beast in terms of IQ.
Better than the Sigma? Because I wasn't impressed with the Sigma at f2.8.
I have never seen test images from a third-party 70-200 or 80-200 that were "impressive" when the lens was shot at f/2.8. In fact, my basic characterization of third-party, $700-$1200 zoom lenses in this category is "not good wide-open", or "decidedly soft wide open". There's a reason Sigma was making 70-200 f/2.8 lenses six years ago, priced at $1,000 lower than comparably-spec'd Canon L-series and Nikon VR-G series lenses...because there are serious design compromises made in order to keep the prices low...either on focus speed, or close-range performance, or flatness of field, or just-slightly-inferior optics,etc,etc. Tokina has been aiming for low-priced knock-off lenses for almost a decade now,competing mostly on build quality and price point.
One needs to read reviews pretty carefully...the Tokina 80-200/2.8 AT-X Pro from what I saw in one review was indeed, as MleeK said, filled with CA. It's an older design that does pre-date digital SLR capture optimization; the thing about a zoom designed for a crop-frame sensor is that the lens needs to have VERY HIGH level optical performance over a small field area, like Nikon's 70-200 VR 1 model had; it was notably better than Canon's 70-200 2.8 L IS USM on APS-C, but the Canon, being years older, was MUCH better across a wider imaging area AKA film or FF. So, Nikon had to re-design a new 70-200, a Mark II version. Canon re-designed it's 70-200 IS USM to a Mark II designation. The Tokina is now what one might say "four or five" generations behind in mechanical technology,and three or four behind in optical design...
I dunno...when a guy looks at a lens that need to be stopped down to f/8 to equalize centers and corners and get away from color fringing....ehhh...even $700 seems like WASTED money to me.
