The 50mm F1.4 DG HSM Art lens is compatible with full-frame DSLR cameras for shooting scenes such as portraits, landscapes, studio work, and still-life. Sigma upgraded the lens in order to allow for close focusing up to 15.7 inches with a max magnification ratio of 1:5.6. The new lens is designed for improved peripheral brightness with a large aperture performance and Special Low Disertion glass.
Sigma also updated the autofocus software in the 50mm Art series lens, which the company states will give users improved focusing capabilities. The new algorithm also includes a floating focus system, which is intended to reduce interference from any lens motion when focusing.
The lens is redesigned with a matte finish as well as a new AF on/off switch. Sigma also assures that each lens is tested before shipping using the company?s own system, which it calls modular transfer function ?A1? measuring system.
Sigma included its own Hyper Sonic Motor technology in the 50mm F1.4 DG HSM Art lens, which the company sates allows for quiet high-speed auto-focusing. The lens also features Super Multi-Layer Coating, which Sigma employs to reduce lens flare and ghosting.
Sigma has not announced pricing or availability for its 50mm F1.4 DG HSM Art lens but the company will have the lens on display at CES 2014 in Las Vegas.
