SIGMA 20mm F2 Contemporary DG DN for Sony E Mount

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 72.4mm 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 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.

Remarkably, the 20mm F2 DG DN | Contemporary is almost identical in size and weight to the very compact SIGMA 24mm F2 I series. A sleek, all metal design, with a signature I series magnetic lens cap, a manual aperture ring and exceptional production quality means using this lens is a highly intuitive and satisfying experience, making the photo-taking process even more enjoyable. This sharp and beautifully built I series prime, the SIGMA 20mm F2 DG DN | Contemporary captures the essence of the I series, bringing a new level of user experience―the pleasure of owning and using a lens.

The SIGMA I series features full-frame compatible lenses that offer new value to mirrorless systems. The combination of superb optical performance with a level of compactness that is perfectly suited to smaller and lighter modern mirrorless cameras will bring you new opportunities for a perfect shot.

SIGMA is aware that in today’s world we have a wide range of camera choices, especially with the increase in mobile phone ownership. But with many photographers looking for something more than something that simply captures images when they choose to own a camera and lens, I series lenses offer the ultimate combination of superb optical performance, outstanding usability and compact form-factor.

SIGMA’s excellence in development and production technologies has been built up since our founding in 1961 and became increasingly sophisticated with the introduction of the SIGMA Global Vision brand in 2012. With this as a base, SIGMA has given careful thought to the quality of the products, the feeling of using it and the pleasure of owning it. This is how the I series was born.
