Overview
Sigma 20mm AF DG HSM Art Prime f/1.4 - Canon EF Mount 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 (5) Special Low Dispersion (SLD) glass in a design of 15 elements in 11 groups. Hyper Sonic Motor (HSM) ensures quiet, high speed and accurate autofocusing.
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.
This lens includes (2) aspherical elements with a total of 15 elements in 11 groups. It offers a minimum focus distance (MOD) of 10.9" (27.6 cm) and a 9-bladed aperture. Filter size not included by manufacturer.
Features:
- Wide angle for full frame or APS-C camera sensors
- Exceptional optical performance ideal for ultra-high megapixel cameras
- Features a 9-bladed aperture with rounded blades
- Quiet, high-speed autofocus
- Includes a large-diameter aspherical lens element
- Minimized chromatic aberation and distortion
