The 50mm T1.5 Cine DS Lens has a minimum focusing distance of 1.5 ft., & features an internal focusing function, which minimizes the effects of lens-breathing, providing a consistent angle-of-view during focus adjustment. Its design features 9 elements in 6 groups, with one aspherical element & one hybrid aspherical element for the reduction of chromatic aberrations. An additional multi-coating assists in improving light transmission, which reduces flare & ghosting. The lens filter thread diameter is 77mm.

This lens is part of Rokinon's DS series of cinema lenses, which all feature the same alignment of their geared focus & aperture rings, enabling follow focus & other rig accessories to eliminate the need for re-adjustment when swapping out lenses. Each of the DS lenses are tested to be color matched with all lenses from the DS series, ensuring the same color & contrast from lens to lens when shooting video. All lenses also are marked with focusing scales on each side of the lens barrel for simple adjustment from both sides of the camera.
