COMMENTS: Sigma's fast 50mm lens with HSM (equivalent to Canon's USM) focusing. Uses a molded glass aspheric elelment to improve image quality. The large front element and barrel help to keep vignetting low, but contributes to weight (and cost). Optically very good. Makes excellent portrait lens on a APS-C DSLR and a great "standard" lens on full frame.
