Sigma Adds Full-Frame 20mm f/1.4 Lens to Art Series

Sigma has announced the launch of 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.

Externally, the lens is manufactured from Thermally Stable Composite material ensuring consistent performance in fluctuating temperatures and reducing the size and weight of the lens. A Hyper Sonic AF Motor provides smooth, fast, and silent focusing, thanks to an optimized AF system; manual focus override is available for fine-tuning down to the minimum of 10.9". Additionally, this focus system and firmware can also be updated later on, using the Sigma USB Dock. The lens also has a nine-blade rounded diaphragm for smooth out-of-focus elements.

The 20mm f/1.4 DG HSM Art lens will be available in Canon EF, Nikon F, and Sigma SA mounts.

The lens is available to pre-order from B&H, with delivery expected at the beginning of December.
