The new Rokinon Cine DS 14mm 3.1 Ultra Wide Angle Cine Lens is one of Rokinon"s newly introduced 2nd generation of cine lenses under its CINE DS line. The Rokinon Cine DS lineup has 3 primary advantages: 1) All of the gears are unified among all Rokinon Cine DS lenses. The focus and aperture gears are exactly aligned so that the user does not have to re-adjust his/her follow focus when swapping out lenses. 2) The new Cine DS lenses now feature dual focusing scales, one on each side. 3) All of the Cine DS lenses are tested to be color matched to provide the same color & contrast in video production.
