Sigma 24mm f/1.4 DG DN Art Lens for Sony E

The Sigma 24mm f/1.4 DG DN Art Lens for Sony E is a fast, wide-angle prime lens designed for full-frame Sony E-mount mirrorless cameras, built as part of the Art line within Sigma’s Global Vision series to deliver astrophotography-level optical performance in a genuinely compact, portable body. It’s well suited to landscape, nature, architectural, and astrophotography work, offering a 36mm full-frame-equivalent field of view when used on APS-C-format Sony cameras.

Optically, the lens is built from 17 elements in 14 groups, including two FLD (fluorite-like low dispersion) elements, one SLD (Special Low Dispersion) element, and four aspherical elements, correcting chromatic aberrations throughout the entire focusing range while significantly suppressing distortion and sagittal coma flare, qualities that make it a strong choice for nightscapes and star photography. Sigma’s Super Multi-Layer Coating minimizes flare and ghosting for contrast-rich, color-neutral images even in backlit conditions, and a rounded 11-blade diaphragm delivers large, pleasing bokeh at the bright f/1.4 maximum aperture.

Autofocus is handled by an STM (stepping motor), delivering fast, near-silent focusing by precisely controlling motor movement and optimizing the screw pitch to match the lens’s optical characteristics, well suited to both stills and video. A Manual Focus Lock (MFL) switch disables the focus ring to prevent accidental focus shifts, and the lens is compatible with AF Assist functionality on select Sony E-mount camera bodies.

Build quality includes a dust- and splash-resistant structure, a water- and oil-repellent coating on the front element, and a rubber seal around the mount, along with a high-precision, durable brass bayonet mount, making it safe to use during extended outdoor shoots. At 510g and 97.5mm in length, it’s approximately 30% lighter and about 16% shorter than Sigma’s earlier 24mm f/1.4 design. The lens has a minimum focusing distance of 9.8-9.9 in. (25cm), yielding a maximum magnification ratio of 1:7.1, and accepts a 72mm front filter thread along with a rear filter holder for sheet-type filter material favored by astrophotographers.

As a full-frame E-mount lens, the Sigma 24mm f/1.4 DG DN Art delivers its full 84.1° angle of view on Sony full-frame bodies while remaining compatible with Sony APS-C E-mount cameras at a narrower, 36mm-equivalent effective field of view.
