The Sigma 20 f/1.4 ART DG HSM lens is an ultrawide lens with a fast F1.4 aperture designed for modern ultra high resolution full frame cameras. The 20mm focal length gives you a very wide field of view and the F1.4 aperture is great for low light or low depth-of-field photography. To ensure edge to edge sharpness this lens uses 15 elements in 11 groups, with “F” low dispersion elements, and five Special Low Dispersion (SLD) elements. The HSM autofocus motor focuses quickly and is silent. As a sign that Sigma is as committed to quality as the photographers using these lenses each is hand inspected and put through its paces on the proprietary “A1” measuring system.
20mm focal length and f/1.4 apertureThe 20mm focal length is a common favorite for photographers who want a lens that consistently makes people say “wow.” Landscapes and interior shots are consistently amazing with this lens, and the fast aperture lets you handhold if you are shooting quickly or in a confined space. The f/1.4 aperture is outstanding for a lens this wide and does a great job at minimizing depth of field or for use in low light photography. The ability to isolate the subject against such an expansive background really brings something new to a serious photographer’s tool kit. The low distortions and edge to edge sharpness of this lens help you get the most out of your photos, even at f/1.4.
