From Sigma UK: 

Introducing the all-new 20mm F2 DG DN | Contemporary from SIGMA. This ultra-compact, wide-aperture prime lens for E-mount and L-Mount systems is a game-changer for mirrorless users needing a sharp, wide-angle optic that isn’t going to weigh them down.

This portable, full-frame premium compact prime for mirrorless cameras is the seventh lens in SIGMA’s fast-growing I series lineup, combining a bright maximum aperture of F2, an ultra-wide 20mm focal length and stunning optical performance. It’s also the widest lens in the range so far, opening up new photographic possibilities for I series users.

The lens boasts an exceptionally small form factor, weighing in at 370g and measuring just 72.4mm in length*, which makes it a highly practical optic that is portable enough for everyday shooting. It’s ideal for landscapes, wide-angle portraits, weddings and interiors, and is particularly well-suited to astrophotography owing to its very well-controlled sagittal coma flare. It’s the fourth I series lens with an F2 aperture, joining a 24mm, 35mm and 65mm, which together make a well-matched lens set for photographers who need both performance and portability in their kitbag. Remarkably, the 20mm F2 DG DN | Contemporary is almost identical in size and weight to the SIGMA 24mm F2 I series. Its sleek, all-metal design, with a signature I series magnetic lens cap, a manual aperture ring and exceptional build quality makes using this lens is a highly intuitive and satisfying experience.
