Sigma 24mm f/1.4 DG DN Art.
Sigma's wide Art for E-mount and L-mount. f/1.4 astro performance at half the price of first-party 24mm GM/L equivalents.
The Verdict.
Gavler Meta-Score
“The value play in the 24mm f/1.4 class: excellent center sharpness, fast silent autofocus, and a pro-grade weather-sealed body with a de-clickable aperture ring — all for roughly half the price of a first-party 24mm f/1.4. The catch is soft extreme corners wide open that don't fully sharpen until f/2–f/2.8, so landscape and astro shooters who need edge-to-edge bite at f/1.4 should stop down or spend up; for everyone else, it's the smart buy.”

Precision Engineering
Excellent Center Wide Open
OpticalLimits rates dead-center quality "very good" at f/1.4; 17 elements in 14 groups (2 FLD, 1 SLD, 4 aspherical), with corners sharpening from f/2.
Fast, Silent STM Autofocus
Dustin Abbott found the stepping-motor AF "silent, extremely fast" with near-perfect accuracy image after image — a leap over Sigma's DSLR-era Art focus.
De-Clickable 11-Blade Aperture Ring
Clicked 1/3-stop ring de-clicks for smooth video pulls, backed by a manual-focus lock switch and both 72mm front and rear filter slots.
Technical Specifications
The Scoreboard
Expert consensus (89) tracks just under the community score (90): reviewers praise the center sharpness, fast STM autofocus, build, and value, while the recurring caveat — flagged most sharply by OpticalLimits — is that border and corner sharpness lag the center at f/1.4 and only reach very good levels from about f/2.8, which softens its astrophotography case.
Cast Your Vote
Do you think Sigma 24mm f/1.4 DG DN Art deserves the #7 spot in Best Wide-Angle Prime Lenses?
Global Critique
“Coma is pretty well controlled, with only a slight bit of "winged" stars towards the edges of the frame. The star points in the center are very sharp and crisp even at F1.4.”
“The Sigma version employed here is one of the best, however, with silent, extremely fast autofocus that delivers good accuracy.”
“The center performance is generally excellent, but the borders/corners leave a bit to be desired at f/1.4 - and being advertised as a lens suitable for astrophotography, that's certainly not ideal.”
“As usual for Sigma Art lenses and priced considerably lower than Sony's similarly specced lens, the Sigma 24mm f/1.4 DG DN Art Lens is a strong value.”
