Hi, This may have been entered before, but I need to know the answer. The Tamron 28-75mm lens on Canon and Nikon verdicts are different.Nikon say resolution very good, while Canon say not to good. Is this because Nikon test it as a crop and Canon as full frame. The lens being poor on the periphery. One remarked "A good lens if you get a good one" Is it a case of "you pays your money and you takes a chance".
