Product Description
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, particularly 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 to date.
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.
As with all Global Vision lines, the 20mm will be tested using the
proprietary A1 measuring system ensuring the highest standard of operation.
The Sigma 20mm Art is compatible with the USB dock to update and customize
and is also compatible with the Mount Conversion Service. A staple procedure for
the Global Vision lines, every lens will be tested using the proprietary A1
measuring system.
