Sigma has just launched two new large-aperture wide-angle lenses in its high-end Art lineup: the Sigma 20mm f/1.4 DG DN Art lens and the Sigma 24mm f/1.4 DG DN Art lens.
The 20mm is being touted as “the ultimate astrophotography lens,” and the 24mm as “an astrophotography lens for everyday use.” Available in L-mount and E-mount, they’re both designed exclusively for use with mirrorless cameras and optimized for full-frame sensors, and while they share a certain set of features, these two lenses are set apart by a few notable differences.
Sigma 20mm f/1.4 DG DN Art lens
Along with a front filter thread, it comes with a rear filter holder, giving you the freedom to combine multiple filters for maximum effect: use a front filter to reduce light pollution in combination with a softening filter on the rear, for instance, to make the most of those starry skyscapes. It’s also equipped with a lens heater retainer, making it easier to attach lens heaters that prevent condensation from forming when the temperature drops on cooler nights. Another handy feature: use the manual-focus-lock switch to turn the focus ring off and prevent accidental changes in focusing distance when shooting in the dark.

Designed to withstand harsher outdoor environments, it features a dust- and splash-resistant structure with a water- and oil-repellent coating of the front element. Ghosting and flares are kept to a minimum by the use of a Super Multi-Layer Coating and Nano Porous Coating, along with the state-of-the-art optical design you expect from a Sigma Art lens. No matter where you plan to take this lens or what you intend to shoot, you’re sure to capture stunningly clear wide-angle images even in the most challenging lighting conditions.
