Ronkonkoma, NY—Sigma Corporation of America introduced the Sigma 20mm F2 DG DN Contemporary lens as part of its premium I series. Moreover, the new lens is the widest I series compact prime released to date.

Furthermore, it is an addition to the fast F2 aperture group of I series lenses, joining the 24mm F2 DG DN C, 35mm F2 DG DN C and 65mm F2 DG DN C. All F2 I series lenses boast an arc-type AF/MF switch and stylized barrel design near the “Made in Japan” marking.

The full-frame premium prime for mirrorless systems boasts a small form factor. It weighs in at 13 ounces and measures approximately 2.9 inches in length. With a metal, knurled, petal-type lens hood, the ultrawide prime is compatible with 62mm threaded front filters.

In addition, its fast F2 maximum aperture makes it a solution for astrophotography. It is also an option for weddings, landscapes, cityscapes, street photography, low-light interior work and other nighttime situations.

What’s more, due to its wide focal length and compact size, the new lens is also a tool for handheld vlogging and video streaming. Content creators will also appreciate the ability to mount front filters, such as neutral density filters, for video and long-exposure landscapes.

Moreover, the new lens provides a minimum focusing distance of 8.7 inches with a maximum magnification ratio of 1:6.7. It also features an all-metal body; a signature I series magnetic lens cap; as well as a manual aperture ring.  

Key Specs

Based on the company’s latest optical design technology, its 13-element, 11-group construction includes three high-precision glass-molded aspherical lens elements; one SLD (super low dispersion) element; and one FLD ( F low dispersion, fluorite equivalent) element. Together, they suppress a range of optical aberrations to achieve clear and sharp images, even in the frame’s corners.

“By focusing on the suppression of sagittal coma flare, which is difficult to correct in post-processing, accurate reproduction of very bright points of light has been achieved. This also provides extremely detailed results across the entire image, especially important for night sky photography,” Sigma added.

Its optical design as well as its Super Multilayer and Nano Porous (NPC) coatings help ensure minimal flare and ghosting, even when shooting into bright light sources. Subsequently, it is easier to photograph backlit subjects and achieve high-contrast results.

Additional Features

The I series lens’s precision-cut aluminum parts not only give the barrel a stylish finish but also provide durability. Metal materials are also used in internal structures that slide with the operation ring. Sigma 90mm f/2.8 DG DN | Contemporary Sigma 90mm f/2.8 DG DN | Contemporary SIgma-Logo-Black covid-19

Indeed, these components crafted with Sigma’s metalworking technology are also used in its Cine lineup for pro cinematographers. In addition, they provide a tactile, ergonomic feel. The cover ring between the focus ring and the aperture ring also has the hairline processing used for the rear cylinder of Sigma’s Art line. This covering functions as a finger hold when attaching or detaching the lens.

In addition, the 20mm lens employs an inner focus system; a 9-blade rounded diaphragm; a focus mode switch; as well as a stepping motor. It is also compatible with high-speed autofocus and lens aberration correction on supported cameras. Plus, it supports DMF and AF+MF.

With a dust- and splash-resistant mount, the lens is also compatible with the Sigma USB Dock UD-11 (sold separately/for L mount only).

In E and L mounts, the Sigma 20mm F2 DG DN Contemporary has a suggested retail price of $699.
