“Ultra-wide-angle lens” that matches the optical performance standards set by the Sigma Contemporary line of lenses.

The Sigma 17mm f/4 DG Comtemporary Lens for Sony E Mount Black 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 Sigma 17mm f/4 DG Comtemporary Lens for Sony E Mount Black 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. This is a lens with truly modern performance, thanks to the advanced processing and production technologies at Sigma’s only production facility in Aizu.

A highlight of using the Sigma 17mm f/4 DG Comtemporary Lens for Sony E Mount Black is the impressive minimum focusing distance of 12cm. Capture close-up macro style images in remarkable detail with expansive backgrounds. It is also suitable for selfies and vlogging, where items need to be shown at an arms-reach.

But with many people look for something more than a mere act of “taking pictures” when they choose to own a camera and lenses, I series lenses offer the ultimate combination of superb optical performance, outstanding usability and compact form-factor. Sigma’s excellence in development and production technologies has been built up since our founding in 1961 and became increasingly sophisticated with the introduction of the Sigma Global Vision brand in 2012. With this as a base, Sigma has given careful thought to the quality of the products, the feeling of using it and the pleasure of owning it. This is how the I series was born.

Exceptional I series build quality with a compact form-factor

The Sigma 17mm f/4 DG Comtemporary Lens for Sony E Mount Black has an all-metal construction.

These high-precision components crafted with Sigma’s cutting-edge metalworking technology are also used in Sigma’s CINE LENS line-up for professional cinematographers and provide a tactile, ergonomic feel that make the lens a pleasure to use. What is more with the I series is that this high build quality is condensed into a palm-sized lens body. The Sigma 17mm f/4 DG Comtemporary Lens for Sony E Mount Black is one of the smallest in the series. Combine with multiple I series lenses to create a remarkably compact shooting system that is lightweight and small in size.
