The Rokinon DS10M-C 10mm T3.1 Cine Wide Angle Lens is a professional-grade cine lens designed for Canon EF-S mount digital SLR cameras with APS-C sensors. It features a fast T3.1 aperture, allowing for excellent low-light performance and shallow depth of field. The lens is constructed with a durable all-metal housing, suitable for rigorous production environments. It incorporates Rokinon's proprietary Nano Coating System to reduce surface reflections and prevent lens flare and ghosting, resulting in improved light transmission and more contrast-rich imagery.
