Sigma has released pricing and availability information of its new 50mm F1.4 DG HSM Art lens. First announced in January at CES in Las Vegas, the 50mm F1.4 DG HSM Art is a completely new lens, rather than a revision of Sigma's existing 50mm F1.4 EX DG HSM. The lens employs the company's Hyper Sonic Motor (HSM) system and has 13 elements in eight groups. It will be available for Sigma, Sony, Nikon, and Canon mounts in late April for $949. The UK RRP will be £849.99.

Sigma Corporation of America Announces Pricing and Availability of 50mm F1.4 DG HSM Art lens

RONKONKOMA– April 11, 2014 – Sigma Corporation of America, a leading researcher, developer, manufacturer and service provider of some of the world's most impressive lines of lenses, cameras and flashes, is pleased to announce that the newest addition to its Global Vision Art camera lens lineup, the 50mm F1.4 DG HSM Art, will be available late April for the street price of $949.

The much anticipated 50mm F1.4 DG HSM Art is a pro-level performer for full-frame DSLRs and is ideal for many types of videography and photography, including portraits, landscapes, studio work and still-life. It has been redesigned and re-engineered with SLD glass and has been optimized for rich peripheral brightness, with improved large aperture performance by positioning wide elements into the front groups.

Other updates to this new lens include an optimized autofocus algorithm for smoother focusing and a floating focusing system to reduce lens movement while focusing. Under the Global Vision line, it features a new matte finish, an updated AF algorithm and every lens undergoes Sigma’s proprietary modulation transfer function (MTF) “A1” testing before being shipped. It has 13 elements in eight groups, compared to the previous eight elements in six groups, and it also has improved close focusing at 15.7 inches and a maximum magnification ratio of 1:5.6.

“Our Art lenses, such as the 35mm F1.4, 24-105mm F4 and 18-35mm F1.8 have been incredibly well received to date, and we couldn’t be more thrilled with the excitement around the news of this upgraded 50mm F1.4,” said Mark Amir-Hamzeh, president of Sigma Corporation of America. “Clearly, the industry is hungry for reasonably priced, powerful, high-quality, multi-purpose lenses – and they’ve seen the image quality that’s being produced by our new Global Vision lenses. There are no sacrifices with these products, and the new 50mm F1.4 is sure to be another star in our lineup.” 

The 50mm F1.4 was first announced at the Consumer Electronics Show this year. It incorporates Sigma’s Hyper Sonic Motor (HSM) system to produce quiet, high-speed auto focus. In addition, it includes Super Multi-Layer Coating to reduce flare and ghosting, and to ensure the highest-quality images. The 50mm F1.4 DG HSM lens is also compatible with Sigma’s USB dock and the company’s Mount Conversion Service.

The Sigma 50mm F1.4 DG will be available in Sigma, Sony (D), Nikon (D), and Canon mounts.
