Sigma is setting new benchmarks for wide-angle image quality with the announcement of the newest Global Vision and market\u2019s first full-frame 20mm F1.4 lens, the Sigma 20mm F1.4 DG HSM Art lens. The lens will become available late November for the street price of $899, and will be available in Sigma, Canon and Nikon mounts.<\/p>\n
This revolutionary prime lens is designed to bring out the full potential of ultra-high-megapixel DSLR cameras. With a focal length of 20mm and F1.4 aperture, this lens delivers outstanding large-aperture brightness and bokeh. Through decades of experience in lens design and Sigma Global Vision lens craftsmanship, the 20mm incorporates both \u201cF\u201d Low Dispersion (FLD) glass, and five Special Low Dispersion (SLD) glass in a design of 15 elements in 11 groups. The combination of advanced optics and optimized lens power distribution minimizes spherical aberration, axial chromatic aberration and field curvature, producing outstanding image quality. 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.<\/p>\n
\u201cWhile many saw the development of a 20mm lens for today\u2019s super-resolution DSLRs as challenging, Sigma approached it head-on utilizing our advanced manufacturing technologies to create the world\u2019s first 20mm F1.4 ultra-wide-angle lens,\u201d said Mark Amir-Hamzeh, president of Sigma Corporation of America. \u201cThis new lens is a result of years of experience by the company\u2019s 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.\u201d<\/p>\n
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.<\/p>\n
This lens is compatible with Sigma\u2019s USB Dock, (sold separately) which allows photographers to update the lens\u2019 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.<\/p>\n
Sigma fans can feel confident knowing that every 20mm lens that leaves Japan\u2019s factory has been tested using Sigma\u2019s own modulation transfer function (MTF) measuring system, \u201cA1.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
