"This is an excellent lens with nice quality finish, quick AF and very nice levels of motor noise - the limit switch it very handy to keep AF at a minimum. Images so far have been extremely sharp and free of Chromatic Aberation. Weighting of the lens on the camera gives a nice solid feel, movements are smooth and precise. Using as a portrait lens the AF is incredibly quick considering the focus is not all internal. Price point is also very nice as images compare (and exceed) those taken with pricier units." bhphotovideo.com

"I bought this in conjunction with the 160fc ringflash, perfect match for this lens.. Aside from being exellent at macro, I found this lens to be stuningly vibrant and contrasty for normal shooting.." bhphotovideo.com
