17mm F4 DG DN | Contemporary

Availability: Translation missing: en.general.icons.icon_check_circle icon In stock, ready to be shipped

Compact, lightweight and high-performance ultra-wide-angle 17mm lens with an impressive minimum focusing distance.

Using the latest technology, the 17mm had been created without compromise, despite its challenging design concept. Its wide-angle of view creates impactful landscape images with a unique perspective and, thanks to its minimum close focusing distance of 12cm, the lens can be enjoyed in a variety of alternative ways, including close-up photography and hand-held selfies.

The optical design has been created exclusively for mirrorless camera systems, which helps reduce lens flare and ghosting that results in excellent image rendering. The all-metal lens barrel highlights SIGMA’s craftsmanship and attention to detail, making the SIGMA 17mm F4 DG DN | Contemporary a pleasure to use on every shoot.
