SIGMA 10-18mm F2.8 DC DN Sony E 207965 camera lens

World's smallest APS-C ultra-wide zoom

The Sigma 10-18mm F2.8 DC DN is a constant-aperture ultra-wide zoom built for APS-C mirrorless cameras. It covers a 10-18mm focal range that delivers a 15-27mm equivalent field of view. Weighing 260g, it is suited to travel, landscape, interior and video creators who need a compact wide-angle option.

Upgrade from variable-aperture kit zooms

Photographers moving from slower variable-aperture wide zooms gain a constant F2.8 aperture across the entire range. The brighter aperture makes low-light interiors and astrophotography more practical without raising ISO. The 11.6 cm minimum focus distance at 1:4 magnification also adds close-up flexibility that basic kit lenses rarely provide.

Steady performance for extended video sessions

A stepping motor drives fast, quiet autofocus with minimal focus breathing, keeping framing stable during rack focus pulls. The constant F2.8 aperture maintains consistent exposure while zooming, avoiding the brightness shifts common with variable-aperture designs. The compact, robust mount and 260g weight keep the centre of gravity close to the body for comfortable handheld gimbal work.
