Summary: I bought this in June 2014 and using it for macro. I am a beginner on macro but this lens will increase the passion for macro :) I am now looking for a lighting solution without giving up a fortune for Canon twin flash type solution.
Summary: This is the only lens that I have seen that allows you to go from Macro to distance photography in one jump. This is a must have for the backpacker who might experience macro on the ground and birds in the air on the same field trip.

Summary: I spent a good deal of time reading reviews before I purchased this lens. It proved to be an excellent choice. I get very positive comments on work I've done with this lens. It is built like a tank and is both solid but also a bit heavy.
Pros: Very sharp, solid build, smooth bokeh, cost effective
Sigma 180mm f/3.5 EX DG IF HSM APO Macro review by elho_cid
6 March 2011
Summary: I own a non-DG versionof this lens, Pentax mount. Pentax version is driven from the camera body, not a HSM. Still with camera like K-5 the AF is instant and accurate, usable for tracking of flying birds or sports. The optics is first class, no reservations.
Pros: sharpnes and bokeh, fast AF
Cons: not compatible with my SuperA or with AF1,7TC (communication problems), AF/MF switch
Summary: Similar to other reviewers,I too had a 105mm Sigma lens prior to purchasing the Sigma 180mm-and I also wanted more distance from the insects I was photographing.After having been stung by wasps when photographing them,I decided the added expense of longer focal length was necessary.Using a Nikon...
Summary: Already in my possession is the older version of Nikon 105mm micro lens, I would like to explore a macro lens of a longer focal length. This lens is reasonably priced (I got it during promotion with the price just slightly higher than the sigma 150mm macro lens) and I have seen breathtaking photos...
Summary: I purchased this lens because I wanted more distance when taking macro photos. As I do with all new lenses I purchase, I calibrate the AF (I have a Nikon D300 with AF Fine Tuning capability). What I found is that the AF on this lens has too much back lash to consistently focus.
Summary: Very strange, I ordered this lens off Amazon about 10 days ago for much, much less. I just got it and it does look to be a gray market lens -- meaning it is meant for sale in another country (I am in the U.S.). The only difference between it and a U.S.
