Overcoming the challenges in assembling a set of lenses over time the Rokinon 14mm T3.1 Cine DS Lens for Canon EF Mount covers full-frame sensors and features a multi-layer coating process for consistent color rendition from lens to lens. It features industry standard geared focus and iris rings that share a common position with other Rokinon Cine DS lenses. This 14mm lens produces a 115.7°, ultra-wide angle-of-view when used with a full-frame sensor. Hybrid aspherical lenses render sharply defined images with a minimum of distortion and chromatic aberrations, and the minimum focus distance is 11" from the lens.
