Sigma 20mm F1.4 DG HSM | Art

Sigma 20mm 1.4 DG HSM Art is a state-of-the-art wide-angle lens designed for full-frame cameras, but will also work with APS-C sensors.

Drawing on over 50 years of lens manufacturing experience, particularly the knowledge gained from the 35mm 1.4 Art and 24mm 1.4 Art, the 20mm 1.4 Art is the widest large-aperture Art lens to date.

The latest optical design enables the highest image quality, with a focus on edge-to-edge performance.

Drawing on decades of experience in lens design and manufacturing of "Sigma Global Vision" lenses, the 20mm lens incorporates both "F" low dispersion (FLD) glass and five special low dispersion (SLD) glass elements, comprising 15 elements in 11 groups.

The combination of advanced optics and optimized lens power distribution minimizes spherical aberration, axial chromatic aberration, and field curvature, resulting in excellent image quality.

This lens, with its class-leading performance, is ideal for landscape photography, videography, astrophotography, low-light/indoor photography and event photography. Like all "Global Vision" lines, the 20mm will be tested using the patented "A1" measurement system to ensure the highest standard of performance. "Sigma 20mm Art" is compatible with a USB dock for upgrade and customization, and is also compatible with the "Mount Conversion Service". The "Global Vision" lines' core procedure, each lens will be tested using the patented "A1" measurement system.
