The Tiny Ultra-Wide

Delivering an expansive field of view in a remarkably compact form, the Sigma 17mm f/4 DG DN Contemporary Lens brings the ultra-wide perspective favored by landscape, street, and architectural photographers into a truly portable package. Designed for everyday use, this lens combines outstanding optical performance with the sleek minimalism of Sigma’s I Series line, making it an ideal choice for creators seeking both form and function.

Compact and Capable Design

Part of Sigma’s Contemporary line, the 17mm f/4 embodies a perfect balance of performance and portability. Measuring approximately 2.5 x 2" and weighing just under 8 oz, it’s light enough for all-day shooting without compromising image quality or durability. Its dust- and splash-resistant build and brass bayonet mount ensure reliable performance in various shooting environments.

Optical Precision

Built with a sophisticated optical design of two SLD elements and three aspherical elements, this lens delivers exceptional sharpness and minimal distortion across the frame. The Super Multi-Layer Coating effectively suppresses flare and ghosting, preserving contrast and color accuracy—even in challenging backlit scenes.

Fast and Smooth Autofocus

Featuring an internal focusing system driven by a stepping AF motor, the 17mm f/4 provides quick, quiet, and precise autofocus performance, making it equally well-suited for both stills and video. It’s also compatible with AF assist and lens aberration correction on supported camera systems for enhanced optical performance.

Creative Close Focus and Bokeh

Despite its ultra-wide perspective, the lens offers a minimum focusing distance of just 4.7 inches, allowing photographers to capture dynamic close-up shots with a sense of depth and scale. Its rounded 7-blade diaphragm produces smooth, pleasing bokeh, adding a subtle artistic quality to backgrounds.
