"The Tamron AF 28-75mm f/2.8 SP XR may shine with glory on APS-C DSLRs but it has found its master within the full format scope"
Not the sort of summing up that makes you want to go out and buy the lens. But is it fair? The corners are a little poorer than the reviewed canon 24-75mm f/2.8 but you have to take into account that it was a single sample with some decentering. The canon was the best of four. Add the canon's field curvature issues and in practice even that selected sample will have questionable corners.
But what made me mad enough to write this rant was your review of the sony 24-75/2.8 It was an excellent review of a decent lens. No "met its match" there. So why trash the tamron that pulled in a better performance at a cheaper price?
