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

“Compact, lightweight and high-performance ultra-wide-angle lens”. 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 lens construction consists of two SLD glass elements and three aspherical lens elements. Aspherical lenses are used for both the front and rear optics. This not only keeps the size of the lens compact but also helps with correcting lens aberrations. As a result, the lens features a φ55mm filter thread (which is smaller than comparable lenses of similar focal lengths) which makes it easy to change filters between SIGMA I series lenses that share the same filter size. Its construction also helps minimize flare and ghosting that is commonly found in ultra-wide-angle lenses, creating clear images in any environment.

SIGMA I series lenses are developed around the concept of “Compact everyday lenses with outstanding image quality” and the SIGMA 17mm F4 DG DN | Contemporary is exactly that. It features high-quality optics in a compact size, perfect for a wide variety of photographic styles.
