I've used the 28-75/2.8 for quite some time and it was pretty good.
Slightly sharper then the Sigma 24-70/2.8 which showed less barrel distortion and is equipped with a bit faster AF, minimal differences though.
Reviews of the this Tamron(and others) can be found on several sites and usually they score a decent result.
The truth lives in one’s mind, it doesn’t really exist
