In the era of mirrorless cameras, the balance between performance and size is even more crucial. There is a growing demand for compact, high-performance, high-quality lenses, and SIGMA responds to this call with the Sigma 20mm f/2 Lens. DG indicates full-frame sensor coverage, and DN indicates mirrorless-exclusive design.
Features
20mm is a very popular ultra-wide-angle focal length, and this new lens is the widest in the I series released to date. Equipped with a metal, knurled, petal-type lens hood, this ultra-wide prime is compatible with 62mm threaded front filters. The new 20mm f/2 DG DN | C features the signature arc-type auto/manual focus switch, dust, splash-resistant mount, and magnetic lens caps. The 20mm f/2 DG DN lens features a distinctive arc-type AF/MF switch and stylized barrel design near the Made in Japan marking.
Fast Aperture
The fast f/2 maximum aperture and total optical performance make this a natural choice for astrophotography, along with landscapes, cityscapes, street photography, low-light interiors, and other night-time situations. Due to its wide focal length and compact size, this 20mm lens is an ideal choice for handheld vlogging and video streaming. And the ability to mount front filters, such as neutral density filters, for video and long-exposure landscapes on such a fast-aperture ultra-wide will be appreciated by many content creators.
Produces Eye-Pleasing Bokeh
The f/2 maximum aperture and overall optical design also deliver pleasing bokeh at the widest F-stops. The 20mm f/2 prime combination offers a consistent fast aperture at four classic cine and still focal lengths.
