Sigma 28-70mm f2.8 DG DN Contemporary Lens for L-Mount

Sigma's 28 70mm f2.8 DG DN Contemporary lens provides uncompromised optical performance, combined with complete flexibility and portability. This lens is lightweight, compact and its versatile focal range and constant f2.8 aperture make it an ideal all day use lens. Despite having fewer glass elements, the lens still sees a complex and advanced lens structure that provides the same professional optical performance as this lens's counterpart, the Sigma 24 70mm F2.8 DG DN Art lens. And, it's that slightly narrower focal range is that allowed Sigma to make this lens 359g lighter, too! This lens is also equipped with various coatings that will further help produce pin sharp images from edge to edge.
