Basic Information

Product Features

Compact, lightweight, and high-performance ultra-wide-angle lens that allows you to get close at will. 17mm lens is now available in the I series!
Compact, lightweight, and high-performance ultra wide-angle lens. This challenging lens has been achieved by applying the latest technologies.
The wide angle of view of 17mm creates a magnificent image with a strong perspective, and the 12cm minimum focus distance allows you to enjoy new ways of using the ultra-wide angle lens, such as close-up photography with a background or hand-held selfies by taking advantage of its small size and light weight. The all-metal lens body, which incorporates the essence of Sigma's craftsmanship, enhances not only the moment of shooting, but also the pleasure of owning the equipment itself. The SIGMA 17mm F4 DG DN Contemporary expands the world of the I-series lenses, which challenge new values as interchangeable lenses for the mirrorless era.

1. "Ultra wide-angle lens" that achieves a new standard of optical performance in the Contemporary line
The lens construction consists of two SLD glass elements and three aspherical lens elements, with the aspherical lens used not only on the first element but also on the rearmost element close to the image sensor to ensure that each aberration is well corrected while keeping the body size down. As a result, a filter diameter of 55mm was achieved for an ultra-wide-angle lens, which normally tends to have a large front. The lens is compatible with front filters and can be used with I-series lenses* that have the same filter diameter. The short minimum focusing distance of 12cm is also a key feature of this lens. The AF drive system uses a quiet, high-speed stepping motor for comfortable shooting of both still and moving images. The lens is designed to minimize flare and ghosting, enabling clear shooting in any environment, even with ultra-wide-angle lenses that are prone to light source intrusion.

*In addition to the 17mm F4 DG DN Contemporary, the I-series lenses with a 55mm filter diameter 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). As of April 2023).

2. I-series lenses offer value beyond "taking beautiful pictures
The I series is a series of full-size compatible lenses that offers new value to mirrorless systems. One of the major advantages of mirrorless systems is that they are compact and lightweight. The combination of high optical performance and compactness that could not be achieved with SLR cameras also creates new shutter opportunities. SIGMA believes that, in this age of mobile devices and other means of photography, owning a camera and lenses is required to have more value than simply "taking pictures. The "I-series" lenses are the result of our deliberations, based on the high level of development and processing technology that we have accumulated since our founding in 1961 and refined through the SIGMA GLOBAL VISION in 2012, and the quality as a tool, the feeling of handling, and the joy of ownership itself. SIGMA Contemporary's answer to the question of what value can be proposed for the existence of lenses today. 3.

3. build quality of I-series specifications
The I-series lenses share the same metal exterior. Parts made of machined aluminum are not only beautiful, but also enhance the quality of the product itself, such as its solid rigidity and high durability. Metal is also used for the internal structure that slides with the control ring. High-precision parts made possible by advanced metalworking technology backed by the SIGMA CINE LENS, a professional-use lens designed exclusively for imaging, give each control unit a superb quality that makes you want to operate it again and again. The appeal of the I series is that this high build quality is condensed into a palm-sized lens body. The 17mm F4 DG DN Contemporary is one of the smallest lenses in the series, but the other I-series lenses are designed to be similar in size and weight, so you can combine multiple lenses to create a remarkably compact shooting system.
