Verdict

In summary, Sigma's 180mm f/2.8 lens is a costly choice for everyday use but a bargain for macro-photography. But there is more to any lens than its price-tag alone and Sigma has produced here a lens of exquisite quality that is not only feature-packed but also capable of yielding both impeccable image quality and beautiful pictures. This is not merely one of the best lenses to have been tested in WDC's reviews, it could even be THE best lens tested so far.
