Tamron Zoom Shootout (28-75, 28-200, 35-150 EF, and 70-180)
50/70mm
The 28-200 is still solidly winning against the 18-135. The gap is narrowing, and I think at this point whatever differences you see in the sample comparisons below are about half real differences and half the different levels of magnification between APSC and FF lenses. The Tamron once again appears so good that I check it against my images from the other day. Last time I said that 70mm still lagged in the tripod test but started looking good in my handheld test. Well today's 70mm tripod image absolutely destroys the 70mm tripod image taken last time, so something went wrong last time. The difference is so dramatic that the third picture is a comparison of the 28-200 last time (left) vs today (right). This is a very good showing at 70mm for the Tamron.
