Sigma has announced a pair of new f/1.4 prime lenses in its Art category, the Sigma 20mm f/1.4 DG DN | Art and the Sigma 24mm f/1.4 DG DN | Art. Both optics are launched for L-mount and Sony E-mount.
Both lenses are positioned among the best lenses for astrophotography (opens in a new tab)thanks to their large focal length, fast aperture to capture light, sharp rendering across the entire frame even at wide apertures, and well-controlled sagittal flare – an aberration that cannot be corrected in post-production.
The Sigma 20mm f/1.4 DG DN | The art features 17 elements arranged in 14 groups, among them a trio of aspherical elements – one of which is “the largest double-sided aspherical element ever produced by Sigma”.
The lens also features a rear filter holder, for simple combination of multiple filters; a clickable and lockable aperture ring; a lockable manual focus ring; and a heater lens retaining lip around the front element to hold a heater strip in place (to prevent condensation forming on the elements).
Its slightly narrower sibling, the Sigma 24mm f/1.4 DG DN | Art, features a total of four aspherical elements and uses a Super Multi-Coating and Nano Porous Coating to combat ghosting and flare, and produce high contrast results in backlit situations.
It also features a water and oil repellent coating on the front lens element, and is also weather sealed to suit shooting in harsh conditions.
Given their focal lengths and claimed rendering ability, both lenses also seem like excellent options for landscape and architectural photography, with the 20mm option looking like a solid bet for videographers thanks to its de-clickable aperture ring.
Both lenses will be released on August 26, along with the Sigma 20mm f/1.4 DG DN | Art priced at $899 / £859 (AU$TBC) and the Sigma 24mm f/1.4 DG DN | Art sale for $799 / £779 (AU$TBC).
