Ultra wide in sight. Tiny in size.

Compact, lightweight and high-performance ultra-wide-angle
17mm lens with an impressive minimum focusing distance.
Now available as a “Premium Compact Prime” I series lens.

“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 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.

Features

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

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. 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 17mm 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. A quiet, high-speed stepping motor drives the AF delivering fast and accurate results in both stills and video.

  • *In addition to the 17mm F4 DG DN | Contemporary, I series lenses with a φ55mm filter thread include the 24mm F3.5 DG DN | Contemporary, 45mm F2.8 DG DN | Contemporary, and 90mm F2.8 DG DN | Contemporary (as of April 2023).

Beyond "beautiful pictures"
―the value provided by the SIGMA’s I series

The SIGMA I series features full-frame compatible lenses that offer new value to mirrorless systems. The combination of superb optical performance with a level of compactness that is perfectly suited to smaller and lighter modern mirrorless cameras will bring you new opportunities for a perfect shot. SIGMA is aware that in today’s world we have a wide range of camera choices, especially with the increase in mobile phone ownership. 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

All I series lenses have an all-metal construction. The precision-cut aluminum parts not only give the barrel a sleek, stylish finish, but provide superb durability that improves the quality of the entire product. Metal materials are also used in internal structures that slide with the operation ring for added robustness. 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 F4 DG DN | Contemporary 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.

Magnetic metal lens cap

I series lenses are accompanied by a dedicated magnetic metal lens cap*, in addition to a normal plastic cap. This dedicated metal cap clips to the front surface of the lens magnetically. It is no exaggeration to say that this meticulously crafted cap represents the finishing touch for the I series.

LENS CAP HOLDER CH-11 (sold separately)

When a cap is removed from the lens it should have a proper place where it can be kept. Using this as a starting point, a cap holder using the magnetic force of the dedicated cap was created.
With the cap attached to the ring plate, and the plate clipped to a bag or belt, the cap is always within easy reach and is less likely to get lost. Plus, its elegant design is a stylish addition to a photographer’s equipment.
