Sigma Announces the 20mm f/1.4 DG HSM Art Lens, the World's First 20mm f/1.4 Lens Designed for Full-Frame Canon, Nikon, and Sigma DSLRs, More Info: B&H

NEW YORK, NY--(Marketwired - October 16, 2015) - The fifth prime lens in the Art line, this 20mm f/1.4 DG HSM is Sigma’s widest offering yet. This revolutionary prime lens is designed to bring out the full potential of ultra-high-megapixel DSLR cameras. Optimized for full-frame high-resolution cameras, it is also compatible with crop sensor cameras, on which it will produce an equivalent focal length of 30mm (Nikon and Sigma) or 32mm (Canon). The wide angle and outstanding image quality make this lens great for seascape, cityscape, and astrophotography, as well as for photos in low light, indoor photography, portraits, and event and wedding photography.

The fast aperture of f/1.4 allows the lens to excel in low-light situations, as well as provide shallow depth of field for selective focus. Nine rounded aperture blades provide smooth and pleasing out-of-focus areas. The lens construction incorporates “F” Low Dispersion glass and five Special Low Dispersion glass elements into a 15-element-in-11-groups design. This helps to minimize spherical aberration and axial chromatic aberration and distortion, providing sharp and contrast-rich imagery, while a Super Multi-Layer Coating reduces ghosting and lens flare.

From the start of the design process, Sigma took steps to minimize flare and ghosting, and established an optical design that is resistant to strong incidental light sources such as backlight with its Super Multi-Layer Coating. As with all Sigma Global Vision lenses, the 20mm f/1.4 lens incorporates the latest Sigma technology, including an optimized autofocus (AF) algorithm for smooth, fast, and accurate focusing. In addition, Thermally Stable Composite (TSC) compound material is used, which has a high affinity to metal parts, consistently performs well at extreme temperatures, and reduces the size and weight of the lens.

A brass bayonet mount adds strength and durability to the lens, and the lens is compatible with the optional Sigma USB Dock, which allows you to update firmware, adjust focus points, and customize manual focus settings. The lens is available in Canon EF, Nikon F, and Sigma SA mounts.

The Sigma 20mm f/1.4 Art lens will feature:

• A Hyper Sonic Motor (HSM) that ensures a silent, high-speed AF function. Smoother AF is achieved when the this AF algorithm is optimized
• A nine-blade, rounded diaphragm creates an attractive blur to the out-of-focus areas of the image
• A brass bayonet mount of highly precise and durable construction to enhance mount’s strength and long-term wear resistance
• Specifications: Weight of 33.5 ounces; a diameter and length of 3.6 inches by 5.1 inches; a minimum aperture of F16; and angle of view (35mm) of 94.5°; minimum focusing distance of 10.9 inches; and a maximum magnification ratio of 1:7.1
