Sigma Adds Three New Lenses: 17mm f/4, 50mm f/2, and 23mm f/1.4

Sigma has announced three new compact prime lenses and the upcoming availability of three existing lenses for the Nikon Z-Mount.

The new Sigma lenses are the 17mm f/4 DG DN, the 23mm f/1.4 DC DN Contemporary, and the 50mm f/2 DG DN Contemporary. The 17mm F4 and the 50mm F2 are full-frame lenses, while the 23mm f/1.4 is designed for APS-C cameras. The lenses coming to the Nikon mount are the Sigma 16mm F1.4 DC DN Contemporary ($499), the 30mm F1.4 DC DN Contemporary ($399), and the 56mm F1.4 DC DN Contemporary ($499).

Sigma 17mm f/4 DG DN Contemporary

The Sigma 17mm f/4 DG DN Contemporary boasts an ultra wide-angle lens designed specifically for full-frame mirrorless systems, weighing 225 grams (in the L-Mount version) and length of 48.8mm.

Sigma says its Cine lenses inspired this lens design. It features a metal barrel with a textured focus ring, an aperture ring, and a lens hood. The 17mm f/4 comes with both metal magnetic and snap-on lens caps. Sigma says it adjusted the focus configuration and shortened the lens’s overall length for a compact body.

The 17mm f/4 DG DN Contemporary lens achieves a close focusing distance of 12 centimeters and a 1:3.6 magnification ratio. The short focusing distance allows for close-up photos with extensive backgrounds, and Sigma says this makes it ideal for vloggers, hikers, and landscape photographers.

Sigma says the lens’s stepping motor allows for swift autofocus for still and video applications. The Sigma 17mm f/4 DG DN Contemporary is $599 and will be available for Leica L and Sony E-mount.

Sigma 50mm f/2 DG DN Contemporary

The Sigma 50mm f/2 DG DN Contemporary is the company’s fifth f/2 “L” series lens, joining the 20mm, 24mm, 35mm, and 65mm lenses.

The 50mm f/2 DG GN is designed specifically for full-frame mirrorless systems. This “standard” prime lens is available in Sony E-mount and Leica L-Mount versions. It features an AF/MF switch and an aperture ring on the all-metal barrel.

Its f/2 maximum aperture delivers what Sigma says is beautiful bokeh. Its optical design produces performance “comparable to the 50mm f/1.4 DG DN | Art lens” in a more compact form (37% shorter length, 48% lighter weight).

The lens is resistant to backlighting and produces minimal flare in challenging conditions. A stepping motor drives fast, reliable AF for still and video use, with Sigma having designed this as a daily all-around lens.

The Sigma 50mm f/2 DG DN Contemporary will retail for $630 and will be available for Leica L and Sony E-mount.

Sigma 23mm f/1.4 DC DN Contemporary

The Sigma 23mm f/1.4 is described as a wide-angle, fast-aperture prime lens specifically designed for APS-C mirrorless systems and offers a 35mm full-frame field of view equivalency on APS-C sensors.

The new lens is the fourth addition to the fast-aperture F1.4 DC DN | Contemporary prime lens lineup, which already includes the 16mm, 30mm, and 56mm versions for crop-sensor mirrorless systems.

Sigma says this lens is designed for optimal mobility with APS-C mirrorless cameras. The lens boasts a compact and lightweight body, weighing 340 grams and measuring 76.9mm in length.

Equipped with a quiet, high-speed stepping motor, the lens offers swift and silent autofocus for both still and video capture. Its excellent flare and ghosting resistance make it ideal for various photography styles, including landscapes, journalism, and everyday photography. The lens has a maximum magnification ratio of 1:7.3 and a minimum focusing distance of just under 10 inches.

The lens is priced at $549 and will be available in Sony E-Mount, Leica L-Mount, and Fujifilm X-Mount. It will be available to order later this month and will ship in “the summer” of 2023.
