The full-frame SIGMA 24mm F1.4 DG DN | Art is a high-performance, wide-angle prime for mirrorless
systems. Available in L-Mount and Sony E-mount, it boasts a very wide F1.4 aperture, making it particularly well-suited to astrophotography as well as a wide range of photo or video applications where a wide angle-of-view and a fast aperture are beneficial.
The lens weighs in at 520g, making it about 30% lighter than Sigma’s existing 24mm F1.4, but it stills gains a range of important new features, including a manual aperture ring with de-click and lock functionality,
a front filter thread and rear filter holder, and an all-new Manual Focus Lock (MFL) switch to fully deactivate the focus ring.
Optically the lens produces very sharp results at all apertures with well-suppressed optical aberrations such as sagittal coma flare. This combination of superb image quality, excellent portability and an advanced feature-set, all built into a beautifully constructed body, make this versatile optic well-suited to both professional imaging and casual everyday shooting.

Key Features:
A wide and fast optic ideal for pro-level astrophotography
The superb optical performance of the SIGMA 24mm F1.4 DG DN | Art is powered by the optimal arrangement of its 17 elements, including two FLD, one SLD and four aspherical elements.
The suppression of a range of optical aberrations such as sagittal coma flare, which cannot be corrected in post, contribute to the lens’s ability to accurately reproduce bright points of light even in the extreme periphery of the frame.
Other unsightly effects such as ghosting and flare are minimized, partly thanks to the use of Super Multi-
Coating and Nano Porous Coating (NPC), helping ensure punchy, high-contrast results in backlit conditions.
The optical power of the 20m F1.4 DG DN to render clean and accurate images in any situation make it perfect
for highly-demanding genres like Astro, landscape and architectural photography.
Portable and light with superb build quality:
The 24mm F1.4 DG DN meets the exceptionally high production standards that users have come to expect from Sigma’s Global Vision lenses.
At 520g it is 30% lighter than Sigma’s existing 24mm F1.4, and about 16% shorter. This reduction in size
and weight is thanks to design changes that have allowed more efficient positioning of internal parts, the
development of more complex aspherical elements, and the freedom afforded by the short flange back
distance. Considering the wide angle-of-view, bright maximum aperture and high optical performance offered
by the 24mm F1.4 DG DN, it is a remarkably portable option that is easily small enough for everyday use.
The robust body is built from a combination of aluminium and Thermally Stable Composite (TSC), giving it a
sleek finish, and the focus ring has a smooth, well damped action. A petal-shaped lens hood is included, and
equipped with a lock mechanism to keep it securely fastened to the lens. A rubber grip makes it easier to attach
and remove the hood.
Built with a dust and splash-resistant structure, a water- and oil-repellent coating on the front element, and a
rubber seal around the mount, the 24mm F1.4 DG DN is safe to use during longer outdoor shoots. *1
The SIGMA 24mm F1.4 DG DN | Art opens up endless possibilities to anyone who values high optical
performance, versatility and convenience, from professional photographers to users who are new to wide-angle
primes.
*1 While the lens is safe to use in light rain, please note that it is not fully weather sealed and therefore not waterproof.
