The 20mm F2 DG DN is a full-frame premium compact prime from Sigma’s I series range. Designed specifically for mirrorless cameras, it features an ultra-wide-angle focal length that is ideal for landscapes, weddings, interiors and astro. Owing to its advanced optical design, which includes three glass-moulded aspherical elements, one SLD element, one FLD element, and nano-porous coatings, the lens delivers exceptional image quality across the frame with very minimal chromatic aberration and well-controlled coma flare.
As with Sigma’s other I series lenses, the 20mm F2 combines superb optical performance with outstanding build quality and retro styling. Its sleek, all-metal body includes a metal focus ring, a metal aperture ring, a metal lens hood, and even a metal lens cap that attaches to the lens magnetically. The lens is essentially designed for photographers and film-makers who value the experience of taking a picture just as much as the quality of the final result.
Weighing less than 400g, the 20mm F2 is portable enough to be carried around for casual day-to-day shooting, but thanks to its outstanding optics, wide F2 aperture, fast AF and impressive build, is equally well-suited to heavy professional use.
