The Sigma 10-18mm f/2.8 DC DN Contemporary is an ultra-compact, high-performance ultra-wide-angle zoom lens engineered specifically for crop-sensor APS-C mirrorless cameras. Providing an expansive 15-27mm full-frame equivalent field of view, it stands as one of the smallest and lightest ultra-wide f/2.8 zooms in its class. Designed to meet the mobile demands of travel visualists, vloggers, landscape photographers, architectural documentarians, and everyday family shooters, it pairs edge-to-edge optical clarity with a fast constant f/2.8 maximum aperture for low-light versatility and shallow depth-of-field control.

The optical design delivers sharp resolution across the zoom span while maintaining minimal optical distortions, fully supported by in-camera and Adobe lens profile corrections for distortion and vignetting. Autofocus is powered by a high-speed, whisper-quiet stepping motor that provides responsive, smooth focus tracking for both fast-paced stills and stable video capture. For dynamic close-up perspectives, the lens achieves an intimate 4.6-inch (11.6 cm) minimum focusing distance at the wide end with a 1:4 maximum magnification ratio. Built with a durable brass bayonet mount featuring a rubber sealing gasket for dust and splash resistance, the lens also includes Sigma’s space-saving push-on petal-style lens hood designed for rapid attachment without adding unnecessary bulk to compact travel kits.
