Tamron Zoom Shootout (28-75, 28-200, 35-150 EF, and 70-180)
135mm
35-150 UL, 28-200 UR, 70-180LL
The 70-180 eeks out a win here. The 35-150 ties it in center, but falls a bit in the corners. The 28-200 still lags a big in the center, but... wait for it... wait for it... IT MAKES A COMEBACK IN THE CORNERS! IT beats the 35-150 in some places and comes within a respectable distance of the 70-180.
NOTE: see my tests on page 3 where I compare the 28-200 vs the APSC 18-135 before drawing any conclusions about the 28-200 at this focal length
