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
If you’re looking to elevate your astrophotography, then this is the lens for you. Designed to deliver sharpness across the entire image area even at maximum aperture, this superb wide-angle prime can capture stars in the night sky as precise pinpoints of light, delivering reliably stellar results and making it the perfect choice for serious astrophotographers.
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.

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.
