Sigma has produced some really fine lenses over the past few years, including the 50mm F1.4 EX DG HSM (which we liked a lot when we reviewed it in 2008 ) and the 85mm F1.4 EX DG HSM . But the 35mm F1.4 DG HSM may possibly be its best yet.

The Sigma 35mm F1.4 DG HSM Art isn't the only third-party option in town. The Tamron SP 35mm f/1.8 has its own set of benefits, including a lower price tag, more uniform illumination, closer focus, and image stabilization.
