Excerpt: great lens, love the minimum focusing distance (12") . solid, but light lens only real complaint is the auto focus. It is loud and can hunt when focusing in close, bu a great lens over all, absolutely recommend this for anyone who does macro.
Excerpt: One of my best lenses, even though I'm also using DA* lenses (Studio (Products and Portraits) & Documentary Reports). Great feeling while focusing, sharp and precise, would highly recommend it!
Excerpt: Outstanding lens for the value. If you can snag this for under $100, you'd be hard pressed to find a better option at a similar price (but that's true for most of the M-series'). Around $175-ish the max for what I would pay for this lens.
Excerpt: I originally bought this lens for medical/scientific work before discovering (to my regret) that I'd over-egged the pudding in terms of focal length and a broader perspective was required (enter its 35mm "little brother", eventually).
Excerpt: I find it very good lens for the first 1:1 macro lens. Closeup AF is ridiculously hunting, but I use manual focus or set clamp on. 1:1 focus is best to be used on a macro rail to help focusing anyway, because even 1mm is notable distance.
