Ph. Reeve: Tamron 24ƒ/2.8 Di III OSD is excellent, “not recommended” unless for macro
#3
I am curious because this defect is so blatant, but other reviewers didn't report it. Could it be a copy defect? Related to hardware or firmware? In the latter case it might be fixed by an update.

Actually all the lenses that I'm using for macro work are mechanically focused (with focusing helicoid, mechanical of course). If I have to use manual focus for macro, it must be mechanical or by wire, but very well implemented. I've never used autofocus in this context, it might help; being slow is not a problem.
