Sigma 20mm f/1.4 DG HSM Art Lens for Leica L Mount Cameras

The Sigma 20mm 1.4 DG HSM Art is a state-of-the-art wide-angle prime lens designed for Full Frame cameras but will work with APS-C sensors as well. Using over 50 years of lens-making experience and the knowledge gained from the 35mm 1.4 Art and the 24mm 1.4 Art, the 20mm 1.4 Art is the widest large aperture Art lens. The latest optical design allows for the utmost in image quality with careful attention paid to edge-to-edge performance. Through decades of experience in lens design and Sigma Global Vision lens manufacturing, the 20mm incorporates both F Low Dispersion (FLD) glass, and five Special Low Dispersion (SLD) glass in a design of 15 elements in 11 groups. The combination of advanced optics and optimized lens power distribution minimizes spherical aberration, axial chromatic aberration, and field curvature, producing outstanding image quality. With class-leading performance, this lens is ideal for landscape photography, videography, astrophotography, lowlight/indoor photography, and event photography.

Optimized AF for L-Mount

With the AF drive control program and high-speed communication tuned for each lens, shooting at speed with high-precision AF control is achieved. The lenses also support the AF-C mode.

Compatible with In-Camera Image Stabilization

Compatible with in-camera image stabilization, the camera automatically detects the focal length of each lens and optimizes image stabilization performance.

Data Pre-Loaded for Compatibility with In-Camera Aberration Correction

Fully compatible with in-camera aberration correction (corrections for peripheral illumination, chromatic aberrations, and distortion). By matching corrections to the optical characteristics of the lens, this function takes image quality to an even higher level.

Native Mount for a More Rigid and Stable Feel

Making the lens mount native provides a much more rigid and stable feel to the lens than using an adapter. Featuring a surface treatment to enhance strength, the brass bayonet mount offers a high-precision fit and exceptional durability. The mount connection area incorporates rubber sealing for dust- and splash-proof construction.

Available SIGMA Mount Conversion Service

This service converts the specifications of the mount of SIGMA lenses to that of a different camera body. Users can tailor their favorite lenses to the camera body if they plan to get a new one in the future. This allows the continued use of their favorite lenses over the long term regardless of the camera system.

Art Lens

Engineered for those who see photography as a critical expression of self, Sigma's Art line offers sophisticated optical performance and abundant expressive power to deliver faithfully on your artistic vision.
