It seems that the optical quality of this lens is not bad at all.
Quoted from the site:
"The shot you see above was taken with that Tamron 70-200mm f/2.8, and during the shoot I switched back and forth between it and my usual Nikon 70-200mm f/2.8 and just looking at the images in Lightroom, at a 1:1 view, neither Brad nor I could see a visible difference between the two"
Of course, I believe the AF speed of the Tamron lens is slower than the other manufacturer. But it is much cheaper.
