Sigma Announces 20mm f/2 DG DN Contemporary Fullframe E-mount Lens


Sigma 20mm f/2 DG DN Contemporary Fullframe Sony E-Mount lens ($699) is a compact prime with f/2 aperture ideal for landscape, cityscape and astrophotography. Wide, bright, and light, it is equally useful as a video lens, and particularly well suited for handheld vlogging and livestreaming.

Optical Design consists of 13 elements in 11 groups, including one F Low Dispersion (FLD), one Special Low Dispersion (SLD), and three aspherical elements. Distortion is minimal, imaging is sharp, and bokeh is smooth. On an APS-C format camera, 20mm turns into a 30mm-equivalent focal length. You can get as close as 8.7 inches from your subject for creative close-ups, a 1:6.7 magnification ratio.

The seventh of Sigma’s I-series of lenses, the new prime shares a number of stylish and functional design features with previous models, including all-metal construction, a manual aperture ring, and knurled controls. Similarly, it measures slightly less than 3 inches in either direction and weighs 13.1 ounces, making it an easy travel companion whether shooting stills or video. A metal lens hood and magnetic lens cap are included, adding yet another layer of functional elegance. Its mount is dust and splash resistant, while its front accepts 62mm filters.
