Sigma 14-24mm F/2.8 DG DN | A

The Sigma 14-24mm F/2.8 DG DN Art is an ultra-wide zoom for full-frame mirrorless cameras. Sigma sells it in Sony E and Leica L versions, so choose the version that matches your camera. The design dates from 2019 and remains in production today.

This range suits interiors, architecture and landscape. At 14mm you can frame a whole room from a doorway. At 24mm you can tighten the composition without swapping lenses. Real-estate shooters can work room after room with one lens. The main trade-off is the feature set: there is no stabilization and no front filter thread.

The lens weighs 1 lb 12 oz (795 g). It measures 3.35 in (85 mm) across and 5.16 in (131 mm) long.

There is no front filter thread, so a screw-in filter will not attach directly to this lens.

The 14mm end is the reason to buy this lens. It frames interiors that leave little room to back up, such as kitchens, hallways and stairwells. Landscapes gain room for a foreground plus sky. The 24mm end lets you trim the scene when 14mm includes too much.

The maximum aperture stays at f/2.8 through the whole zoom. In a dim church or at blue hour, that extra light keeps handheld work practical. It also suits star fields at 14mm, where a wide view gathers plenty of sky. Depth of field stays deep at these focal lengths, so the main benefit is working light, not subject separation.

Close focus sits at 0.9 ft (28 cm). You can move near a foreground detail, a doorway latch or a rock, and make it larger in the frame. The wide perspective then stretches the gap between that detail and the background. Distant subjects stay small at these focal lengths, so this lens serves whole scenes rather than isolated far details.

Our specification assessment scores the optics 82 out of 100.

Weather sealing is built in, adding a barrier against dust and moisture entering the lens. Landscape and architecture shooters working outdoors get that added protection.

A fluorine coating on the front element helps water and oil slide off. Smears and sea spray wipe away more easily, which matters on a lens you will clean often in the field.

The lens offers no built-in stabilization. At 14mm, small camera movements show less in the frame than they would at a long focal length. Even so, the lens itself adds no steadying help. There is also no zoom lock to keep the barrel from creeping.

The optical design includes 18 elements in 13 groups, with aspherical elements and low-dispersion glass. The aspherical surfaces help correct distortion and spherical aberration. That matters for architecture, where distortion can curve straight walls and doorframes. The low-dispersion glass helps reduce chromatic aberration, which shows as coloured fringes along high-contrast edges such as lit windows at dusk.
