Sigma 20mm F2 Contemporary DG DN for L Mount

The balance between performance and compactness is even more important in the age of mirrorless cameras. The Sigma 20mm f/2 Lens responds to the growing demand for compact, high-performance, high-quality lenses.

Widest Lens in the I Series

The 20mm focal length is a popular ultra-wide-angle lens, and this new lens is the widest in the I series to date. This ultra-wide prime is compatible with 62mm threaded front filters and comes with a metal, knurled, petal-type lens hood. The new 20mm f/2 DG DN | C has an arc-type auto/manual focus switch, as well as a dust and splash-resistant mount and magnetic lens caps. The 20mm f/2 DG DN lens has a styled barrel design and an arc-type AF/MF switch near the Made in Japan marking.

Fast Aperture

Landscapes, cityscapes, street photography, low-light interiors, and other night-time scenarios benefit from the fast f/2 maximum aperture and overall optical performance of this lens. This 20mm lens is great for handheld vlogging and video streaming due to its wide focal length and small size. Many content makers will appreciate the ability to mount front filters, such as neutral density filters, for video and long-exposure landscapes.

Produces eye-pleasing bokeh

At the widest F-stops, the f/2 maximum aperture and overall optical design produce beautiful bokeh. At four classic cine and still focal lengths, the 20mm f/2 prime combination provides a steady fast aperture.
