Tamron Zoom Shootout (28-75, 28-200, 35-150 EF, and 70-180)
50mm
35-150 UL, 28-200 UR, 28-75 LL
Once again the 35-150 and 28-75 seem to trade blows, but there was a definite front/back focus between the two with the 35-150 being much better in the far background and the 28-75 being much better in the extreme foreground and the lenses about tying in the middle. The 28-200 makes up some ground to these two after it's absolutely lousy 35mm performance, but still trails them both noticeably.
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
