My copy of the 18-135 was absolute crap. My copy of the 16-70 is really good. I didn't pursue a second copy of the 18-135. If you think you have a keeper, then keep it. Oh, and, don't let other people tell you how you should or should not test a lens.


ofc you should let others tell you how to test a lens if you do it wrong - if its outside in the wind and they have different amounts of movement then the test is utterly useless.

(though i am not certain this was outside?)

probably enough for someone to declare their copy of a lens was absolute crap regardless of its quality

with the shots above - comparing at f5.6 shows the 18-135 as better but the 16-70 at f4 to be better

as the test data on 16-70 suggests 5.6 is its sharpest it should be the other way round if anything indicating test flaw or large sample variation
