Prime Lens with a Focus on Detail

The Sigma 20mm f/2 DG DN Contemporary Lens for Leica L-mount offers a sleek, compact design alongside exceptional edge-to-edge sharpness, all housed within a stylish all-metal construction. Perfect for capturing landscapes, cityscapes, handheld vlogging, and video streaming, this lens boasts a modestly bright f/2 maximum aperture, ideal for low-light conditions and achieving shallow depth of field effects. Its fast maximum aperture also positions it as a prime choice for night sky and astrophotography enthusiasts. With a focus on ease of use, this lens incorporates a stepping motor for swift, precise, and silent autofocus performance, catering to both photo and video applications seamlessly.

Refined Optics

  • As part of the Contemporary line within Sigma's Global Vision series, this lens is designed to achieve a balance between convenience and performance and meshes a compact, lightweight build and versatile handling with notable optical attributes.
  • The lens is constructed with one SLD glass element and one FLD glass element to correct chromatic aberration. It incorporates three high-precision aspherical elements, which reduces the total size and weight of the lens.

Physical Design

  • I-series lens emphasizing a sleek and stylish physical design built to the same operational standards of Sigma's Cine lenses, including a mechanical aperture ring, knurled metal components, and various switches and tactile controls for intuitive operation.
  • Wide-angle 20mm lens designed for full-frame Leica L-mount mirrorless cameras, however, can also be used with APS-C models where it provides a 30mm equivalent focal length.
  • Bright f/2 maximum aperture strikes and ideal balance between speed and size and manages to maintain a compact physical profile while also offering low-light performance and depth of field control.
  • Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.

Fast Closeup Focusing

  • Integrated stepping motor realizes smooth and quiet autofocus. Full-time manual focus control can also be selected via an arc-type auto/manual focus switch. A newly designed linear/non-linear manual focus function is also available.
  • Minimum focusing distance of 8.7" for unique close-up shooting capabilities.

All-Purpose Functionality

  • All-metal body and high-precision metal parts with a dust- and moisture-resistant lens mount for increased protection from the elements.
  • Metal lens hood helps to reduce lens flare when working in strong lighting conditions and also offers some protection to the front element of the lens.
  • Compatible with optional CH-11 Magnetic Cap Holder, which features a mini-carabiner for clipping to a bag, jacket, or belt loop.
