The Tiny Ultra-Wide
Packing a huge field of view in a diminutive size, the Sigma 17mm f/4 DG Contemporary Lens offers the ultra-wide perspective beloved by landscape shooters, street photographers, and those working with interior and architectural subjects in a compact, portable size for everyday use.
This wide-angle prime pairs its broad perspective with a modest f/4 maximum aperture, which helps to keep the overall size and weight as small as possible, and capable optics to render scenes with high sharpness, accuracy, and low distortion.
An ultra-wide like this is a perfect partner for lightweight landscape kits, everyday shooting of architecture subjects and interior scenes, and even as a creative option for unique portraits and vlogging.

- Internal focusing design pairs with a stepping AF motor for responsive and fast focusing performance that's suitable for both stills and video applications.
- Optical design includes two SLD elements and three aspherical elements, to optimize sharpness and limit distortion, and a Super Multi-Layer Coating that controls flare and reflections.
- Close minimum focusing distance of just 4.7" suits working with close-up subjects.
- Rounded 7-blade diaphragm contributes to a smooth and pleasing bokeh quality.
- Dust and splash-resistant construction with a brass bayonet mount for ensured accuracy and durability.
