The Samyang 50mm F1.2 AS UMC CS lens is a manual focus lens for interchangeable lens cameras equipped with an APS-C or smaller sensor. Equivalent to a short telephoto lens, corresponding to 75mm on a 1.5x APS-C sensor, 80mm on a 1.6x crop (Canon M) or a 100mm lens on a 2x MFT sensor, it is an excellent lens for tight portraits and other applications requiring a bright short telephoto lens. With a relatively compact size and weight for a lens of such aperture, the result is a compact, easily portable and discreet lens, perfect for street photography in low light. The Samyang 50mm f1.2 is a fully manual lens, with a bright f1.2 aperture, combined with a 9-blade circular aperture diaphragm offering beautiful bokeh and background separation with a shallow depth of field. This lens comprises 9 elements arranged in 7 groups, including 2 aspherical glass (ASP) lens elements to deliver 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 construction is made from high-strength aluminium alloy. As the lens is specifically designed for compact system cameras (CSC) such as Sony NEX / ILCE, Olympus PEN / OM-D, Panasonic Lumix G, Blackmagic MFT, Fujifilm X and the Canon EOS M series, the Samyang 50mm f1.2 is compact and lightweight, weighing less than 390g, making it a highly portable lens for such an aperture.
