Rated 4.5 out of 5 stars by 22 users at B&H Photo Video

"This lens is a must-have for macros at a great price. I am thoroughly enjoying the sharp 1:1 macros. Last weekend I used it as a 90mm portrait and the results were excellent too."

"This Tamron macro is a classic and has performance to back it up. It is sharp wide open and sharpness does not drop until f/16. Relative to the Pentax 100 f/3.5 macro, this Tamron is a tank."

"Only minor concern being difficulty in moving from manual to auto with lens hood in place."
