Re: +1 to what Michael said..

I have been using all of Sigma's ART lenses as well as their 180mm APO Macro for a number of years. In addition I own Nikon and Zeiss 135mm APO. The nikon's I would put at the bottom of the barrel and rate the Sigma ARTs almost as good as the Zeiss Otus 85mm f1.4 that I own. The Sigma 85mm f1.4 ART is superb.
