Utilizing a multi-layer coating process for consistent color rendition from lens to lens the Rokinon 35mm T1.5 Cine DS Lens answers the challenge of assembling a set of lenses over time. The lens comes in Canon EF Mount and features industry standard geared focus and iris rings that share common position with other Rokinon Cine DS lenses. To aid focus pullers who have to work both sides of the lens, the aperture and focus scales are marked on both sides of the lens.

This 35mm lens produces a 63.1° angle-of-view when used with a full-frame sensor camera or a 35mm SLR. Hybrid aspherical lenses render sharply defined images with a minimum of distortion and chromatic aberrations, with a minimum focus distance of just under 12″ from the lens. A removable petal shaped lens hood provides flare protection when shooting without a matte box, the lenses threaded front accepts a 77mm filter ring.

Please note that some cameras may require that Shutter Lock be disengaged when using this lens.

The 50mm T1.5 AS UMC Cine DS Lens for Canon EF Mount from Rokinon is a fast manual focus prime lens. It provides a very fast maximum aperture of T1.5 for effective low light capture and shallow depth of field control and an 8 blade iris for attractive bokeh. Optimized for cinema and video applications, the focus and aperture control rings are outfitted with industry standard gearing, which provides an interface for working with a traditional follow focus. The aperture control ring has also been de-clicked, which enables smooth iris pulls. In addition, bright aperture and distance markings are printed on the lens barrel facing laterally to facilitate easier control by a focus puller.

The 50mm has a minimum focus distance of 1.5′. Internal focusing minimizes the effects of lens breathing, which insures a more consistent angle-of-view when adjusting focus. The lens is composed of 9 elements in 6 groups, including one aspherical element and one hybrid aspherical element to reduce aberrations. In addition, a lens multi-coating helps to improve light transmission reducing flare and ghosting. The filter thread diameter is 77mm.

With this 50mm lens, Rokinon introduces the DS series of cinema lenses, unifying their cine lenses in more than just name. Each of the DS branded lenses will offer the same alignment of their geared focus and aperture rings so that follow focus and other rig accessories won’t need re-adjustment when swapping lenses. Also, each DS lens is tested to be color matched with the other lenses in the series and provide the same color and contrast when shooting video. Lastly, the lenses are marked with focusing scales on each side of the barrel for easier adjustment from either side of the camera.
