The Rokinon 14mm T3.1 Cine ED AS IF UMC Lens was developed primarily for film and video applications. The cine version of Rokinon's 14mm lens features industry-standard gearing for the focus and aperture ring, and the aperture ring has been de-clicked for smooth iris pulls. The aperture and focus scales have also been relocated to the side of the lens, where it is easier for focus pullers to read them.
