Overview

20mm F2 DG | Contemporary

Exceptional optical performance and superb build quality give photographers the joy of creating images.

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.

Key Features:

  • Lens construction: 13 elements in 11 groups, with 1 FLD, 1 SLD and 3 aspherical lens elements
  • Inner focus system
  • Compatible with high-speed autofocus
  • Stepping Motor
  • Compatible with Lens Aberration Correction
  • *Function available on supported cameras only. Available corrections may vary depending on the camera model.
  • Support DMF and AF+MF
  • Nano Porous Coating
  • Super Multi-Layer Coating
  • Aperture ring
  • Focus Mode Switch
  • Petal-type lens hood (LH656-03)
  • Magnetic metal lens cap (LCF62-01M)

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.
