SIGMA 20mm F2 DG DN | Contemporary
Dynamism in the palm of your hand
Exceptional optical performance and superb build quality give photographers the joy of creating images – introducing the new ultra-wide SIGMA 20mm F2 DG DN | Contemporary
This all-new full-frame premium compact prime for mirrorless systems is the latest addition to SIGMA’s I series lineup, combining a bright maximum aperture of F2, an ultra-wide 20mm focal length and stunning optical performance.
The lens boasts an exceptionally small form factor, weighing in at just 370g and measuring just 72.4cm 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 is the fourth I series lens with an F2 aperture, joining a 24mm, 35mm and 65mm, which together make a well-matched lens set for L-Mount and Sony E-mount users.
