Tamron Zoom Shootout (28-75, 28-200, 35-150 EF, and 70-180)
24/35mm
The 28-200 wins everywhere again. It's definitely noticeable. Chock some of the victory up to the 300% magnified view of the 18-135, but it's definitely still there when both are viewed at 200%. The thing is that the 28-200 looks pretty dang good here after I said it fell apart at 35mm and infinity when comparing it to the other FF lenses. So I went back and compared today's shot from the shot taken the other day. The truth is that it is not that different. Any major differences can be summed up by autofocus inaccuracies by using AF-S and not MF, heat shimmer (as it was at least 15-20*F hotter last time than it was today), significantly different lighting between the two days, and the fact that the last test I think I zoomed into a ridiculous 400% at 35mm for the sake of comparison (vs 200% this time). It is still too soon in the comparison to make a definitive conclusion, but I'm thinking I might have given the 28-200 a bad rep in the middle focal range too quickly. When compared to another good lens/camera setup it is doing pretty good this time.
