The Samyang 50mm T1.3 AS UMC CS VDSLR / Cinema lens is the film/video version of the Samyang 50mm f/1.2 AS UMC CS lens, offering the same superb optics, but with a built-in gear for follow focus systems on video equipment, including de-clicked aperture and T-stop values. Cinema lenses allow more precise control during shooting, the de-clicked aperture operates silently and smoothly, and distance scales and T-stop values are marked on both sides of the lens for convenient use.


The Samyang 50mm T1.3 lens is a fully manual lens, including manual focus, specially designed for mirrorless cameras with APS-C or smaller sensors. Equivalent to a short telephoto lens, it corresponds to 75mm on an APS-C sensor with a 1.5x crop factor, 80mm on a 1.6x crop (Canon M) and a 100mm lens on an MFT sensor with a 2x crop. The Samyang 50mm T1.3 cinema lens is an excellent lens for close-up portraits and other applications requiring a short, fast telephoto lens. Its relatively compact size and weight for a large-aperture lens make it easily portable and unobtrusive, ideal for street videos or low-light shoots or for spontaneous shots.


The Samyang 50mm T1.3 is a fully manual lens, with a fast aperture of T1.3 / f1.2, along with a 9-blade circular diaphragm offering beautiful bokeh and background separation with shallow depth of field work, particularly useful for achieving a cinematic look.


This lens comprises 9 elements arranged in 7 groups, including 2 aspherical glass elements (ASP) to provide high resolution and edge-to-edge sharpness across the entire image. Samyang Optics' Ultra Multi Coating (UMC) treatment is used to optimise light transmission and minimise artefacts such as internal reflections, flare and ghosting.


The solid lens frame is made from high-strength aluminium alloy, compact and relatively lightweight for a large-aperture lens, weighing approximately 400g. The lens is specially designed for compact system mirrorless cameras (CSC) such as Sony NEX / ILCE, Olympus PEN / OM-D, Panasonic Lumix G, Blackmagic MFT, Fujifilm X and the Canon EOS M series.
