Tamron Zoom Shootout (28-75, 28-200, 35-150 EF, and 70-180)
50mm
35-150 UL, 28-200 UR, 28-75 LL
The 35-150 is the definite and clear winner and is excellent. The 28-75 is close behind in the corners and midframe, but is noticeably the worst at center. The 28-200 is the second best at center and lags both the 35-150 and 28-75 in corners and midframe, but not by nearly as much as my infinity tests on a tripod. Once again, these are respectable showings and not quite the complete "the mid-range focal lengths completely fall apart" narrative that my initial tests suggested.
The 28-75 and 28-200 still do not seem to suffer from lack of lens stabilization (the 35-150 has it)
