This cinema-quality lens from Rokinon has been specifically constructed for full-frame cameras, and provides the most wide-angle shots and videos possible while maintaining the quality a professional demands. Thanks to Rokinon's uniform gearing across their cinema lens range, there's no need to re-adjust for follow focus. The lenses also feature dual focusing scales and color matching to keep the transitions seamless and eliminate the need for extensive color or tone correction in post production. The use of multiple aspherical elements creates incredibly sharp images, with little to no distortion or color-related inconsistencies. The aperture on this lens is also click-free, allowing for the smoothest possible operation, and everything is calibrated in T-stops to provide accurate and consistent exposure. The lens features an integrated petal-style hood to eliminate most lens flares, no matte box needed, and the lens barrel features identical markings on both sides so that you and a partner or assistant can both know what's going on at all times.
