Sigma 17-40mm F1.8 DC Art Standard Zoom Lens - Sony E-Mount

The Sigma 17-40mm F1.8 DC Art is the first Art lens for APS-C format cameras since 2016—and the very first designed exclusively for crop-sensor mirrorless systems. It offers an expanded zoom range that delivers both a wider angle of view and greater telephoto versatility.

Tailored for today’s hybrid creators, it excels in video as well as stills, thanks to its internal zoom mechanism, high-speed and silent linear autofocus, and minimal focus breathing. Built for real-world use, the lens also features a dust- and splash-resistant construction to perform reliably in demanding environments.

Weighing just 535g (18.9 oz.), the 17-40mm F1.8 DC Art is significantly lighter than its predecessor while offering professional-grade features that appeal to photographers, filmmakers, and content creators alike—no matter what APS-C mirrorless system they use.
