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.

“While many saw the development of a 20mm lens for today’s super-resolution DSLRs as challenging, Sigma approached it head-on utilizing our advanced manufacturing technologies to create the world’s first 20mm F1.4 ultra-wide-angle lens,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “This new lens is a result of years of experience by the company’s optical engineers in developing state-of-the-art lens designs and proven production knowledge, and high-precision craftsmanship by our factory team in Aizu, Japan.”

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 F1.4 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.

This lens is compatible with Sigma’s USB Dock, (sold separately) which allows photographers to update the lens’ firmware, adjust focus points and customize full-time manual focus over-ride function settings using Sigma’s Optimization Pro software. A new metal lens cap (LC907-02) is also available as a separate accessory for $23.

The Sigma 20mm F1.4 Art lens will also 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

Sigma fans can feel confident knowing that every 20mm lens that leaves Japan’s factory has been tested using Sigma’s own modulation transfer function (MTF) measuring system, “A1.” Other prime lenses in the Art line include: 24mm F1.4 DG HSM, 30mm F1.4 DC HSM, 35mm F1.4 DG HSM, and 50mm F1.4 DG HSM.
