Sigma Adds Full-Frame 20mm f/1.4 Lens to Art Series1 min read
Reading Time: < 1 minuteEveryone seems to be looking wide in the days leading up to PhotoPlus Expo 2015, with Sigma making the latest splash in the wide-angle-lens pool by announcing the 20mm f/1.4 DG HSM Art. This is the first 20mm f/1.4 lens designed for full-frame cameras and joins the already impressive Art prime line consisting of 24mm, 35mm, and 50mm f/1.4 options. These lenses are known for their ability to realize the potential of modern high-resolution image sensors and advanced optical designs, so for those looking to get ultra-wide, this should be a much appreciated option.
Being the first full-frame capable 20mm lens with an f/1.4 aperture, it is well-suited to landscapes, astrophotography, event shooting, and low-light work. Also, when used on APS-C format cameras, it will offer a still quite versatile 30mm equivalent focal length. Optical quality is ensured through the use of both “F” Low Dispersion glass and five Special Low Dispersion elements in the 15-element-in-11-group design. These optics work to minimize spherical and axial chromatic aberrations and field curvature, while a Super Multi-Layer Coating resists flare and ghosting, resulting in clean, distortion-free images.
