Sigma is adding two wide-angle prime lenses to its premium Art lens family—the Sigma 20mm f/1.4 DG DN Art and the Sigma 24mm f/1.4 DG DN Art lens for Sony E-mount and L-Mount full-frame digital cameras. With features designed to control sagittal coma flare, special lens coatings, and much more, these new lenses are sure to satisfy the needs of astrophotographers, nighttime landscape photographers, and others.

Sigma 20mm f/1.4 DG DN Art
The new Sigma 20mm f/1.4 DG DN Art lens is the widest-aperture Sigma 20mm prime now available for the Sony E-mount and L-Mount cameras, surpassing the Sigma 20mm f/2 DG DN Contemporary, while also earning the flagship Art designation. This lens joins the DSLR-mount Sigma 20mm f/1.4 DG Art lens—the world’s first f/1.4 20mm lens. The new lens’s “DN” designation signals that the glass was built specifically for mirrorless cameras.

This wide-angle lens is designed for sharp performance from corner to corner and has been engineered to control sagittal coma flare and distortion. These characteristics, as well as special lens coatings, are designed with astrophotographers in mind, who will love to get pin-point accurate stars across the full field of view.
The lens accepts an 82mm front filter, and rear filters, for various effects. Both front and rear filters may be employed simultaneously. A Manual Focus Lock (MFL) switch disables the focus ring, keeping focus locked. Another feature for outdoor photographers, in daylight and darkness, is the Lens Heater Retainer—a curved lip at the front of the lens designed to keep a lens heater from causing vignetting on this wide-angle lens.

An 11-blade rounded aperture diaphragm is housed between 15 groups of 17 lens elements that include 2 SLD lenses and 3 aspherical elements. For video shooters, the lens features an aperture ring click switch and a near-silent stepping focus motor. While the wide-angle nature of this 20mm prime lens necessitates the wide 82mm opening, the lens is compact overall and similarly sized to the Sigma 35mm f/1.4 DG DN Art lens.
Sigma 24mm f/1.4 DG DN Art
Also new to the Art family, the Sigma 24mm f/1.4 DG DN joins the current Sigma 24mm f/1.4 DG Art lens for Sony E- and L-Mount cameras and the DSLR-friendly Sigma 24mm f/1.4 DG HSM Art lens. The new lens carries the mirrorless-specific “DN” designation and, like the new 20mm f/1.4 discussed above, the 24mm f/1.4 DG DN boasts similar features and functionality as its wider stablemate, for Sony E-mount and Leica L bodies.

Like the 20mm, the 24mm accommodates a front 72mm filter and a rear filter holder for combining filters. The 24mm also has the MFL switch that disables the focus ring and keeps focus locked, even if the lens is handled without care.
Optically designed to reduce sagittal coma flare significantly, as well as distortion, the lens was created with astrophotography and nighttime landscape photographers in mind. Additionally, with compatible cameras, the lens allows aberration correction for additional image quality. The quiet stepping motor and aperture ring click switch make the lens great for videography. 11 rounded aperture blades restrict light through the lens’s 17 elements arranged in 14 groups.

Seems like such a versatile lens that I would use this for many shoots, video and photo and 1.4 is pretty darn fast. Jake achieved beautiful DOF in his shots. The price seems reasonable too.
