The Rokinon 50mm is a fully manual cine lens designed for Canon EF-mount cameras and camcorders. Each of the lenses in this DS line has been specially tested for color matching so that you get consistent output across the entire collection.

Normal-Range & Aperture
The Rokinon 50mm T1.5 AS UMC Cine DS offers full-frame coverage, giving you a budget-friendly normal-range cine lens. Its T1.5 aperture enables both low-light shooting and depth-of-field control. Internal focusing minimizes the effects of "breathing" and ensures a more consistent angle of view during focus adjustments.

50mm T1.5 Cine DS has an advanced optical design for high-quality images. The lens is composed of 9 elements in 6 groups, including one aspherical element and one hybrid aspherical element to reduce distortion and chromatic aberrations. The UMC coating improves light transmission, thereby reducing lens flare and ghosting.

Completely Manual
The Rokinon 50mm T1.5 DS Cine EF Mount Lens is a very fast, manual focus cinema prime designed for filmmakers. It provides no electronic communication with the camera. All aperture and focus adjustments are made manually on the lens itself. The aperture selected will not be displayed on the camera, and it won’t show up in the EXIF data.

Cine DS
Each lens in the Cine DS series shares common focus and iris gear ring positions, enabling quick and easy lens change when using a follow focus. A multi-layer coating process offers color matching across the Cine DS line for consistent results regardless of focal length.

Cine DS Build
The stepless, 0.8 pitch gear aperture and focus rings allow you to use follow focus without the need for clunky gears. 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. A removable petal shaped lens hood provides flare protection when shooting without a matte box; the lenses threaded front accepts a 77mm filter ring.

Movri Canada, providing the mail-delivery system, is set out to make the gear available at more affordable prices through online rentals.
