Sigma 10-18mm F/2.8 DC DN Contemporary Lens (Sony E)

World’s Smallest, Lightest Ultra-Wide Zoom for APS-C Mirrorless The Sigma 10-18mm F/2.8 DC DN Contemporary is an ultra-wide-angle zoom lens purpose-built for Sony E-mount APS-C mirrorless cameras, covering a 15-27mm full-frame equivalent focal range. Recognized as the world’s smallest and lightest F2.8 zoom lens of its kind for APS-C cameras, it combines premium optics, a bright constant aperture, and a compact, travel-friendly build, making it an excellent choice for landscape, architecture, travel, and vlogging work.

Versatile Ultra-Wide Focal Range

With a 10-18mm focal length (15-27mm full-frame equivalent) and a 109.7° angle of view, this lens enables expansive, dramatic compositions well suited to landscapes, interiors, and architecture. Its constant f/2.8 maximum aperture holds steady throughout the zoom range, giving photographers consistent exposure and framing flexibility whether shooting wide cityscapes or tight interior spaces.

Premium Optical Formula for Sharp, Clean Images

The lens features an advanced 13-element, 10-group optical design incorporating three FLD (F Low Dispersion) elements, one SLD (Special Low Dispersion) element, and four aspherical elements, including a unique aspherical element that helps reduce the lens’s overall size while enhancing image quality. This formula works to correct chromatic aberration and color fringing, delivering sharp, high-contrast results across the entire frame.

Super Multi-Layer Coating to Minimize Flare

To further protect image quality, the lens is treated with Sigma’s Super Multi-Layer Coating, which helps minimize lens flare and ghosting even in strong or backlit lighting conditions. This coating helps maintain high contrast and clarity, making the lens dependable for shooting toward bright light sources or in challenging outdoor scenes.

Fast, Quiet Autofocus for Photo and Video

An integrated stepping autofocus motor delivers fast, quiet, and smooth focusing performance, supported by an optimized AF algorithm and minimal focus breathing that make it well suited to video work. The internal focusing design keeps the lens’s physical length constant during use, and its light weight allows it to be easily mounted on a motorized gimbal for professional or social media video content.

Compact, Rugged, Weather-Resistant Build

Measuring just 62.0mm in length with a 72.2mm maximum diameter and weighing only 260g, the lens is remarkably compact and easy to carry for everyday shooting or travel. Its mount features a dust- and splash-resistant structure with rubber sealing, paired with a high-precision, durable brass bayonet mount for long-term reliability in the field.

Close Focusing and Convenient Push-On Hood

The lens offers a minimum focusing distance of 11.6cm (4.6 inches) with a 1:4 maximum magnification ratio, enabling creative close-up compositions with expansive backgrounds and pleasing bokeh from its rounded 7-blade diaphragm. A newly developed push-on petal-type lens hood attaches via a spring-and-lever mechanism rather than a traditional twist-on design, keeping the lens sleek and travel-ready.
