Sigma reveals prime lens treats for everyone except Canon fans

Sigma has just taken the wraps off several exciting new prime lenses for most of the major mirrorless camera systems, except Canon.

The big news for anyone who's looking for a bright, affordable prime lens for street or portraiture is Sigma's new pair of Contemporary series lenses. The 17mm f/4 DG DN ($599 / £549) and 50mm f/2 DG DN ($639 / £619) are both full-frame lenses that are designed for Sony's E-mount and the L-Mount favored by Panasonic and Leica cameras.
