The Samyang 24mm T1.5 ED AS IF UMC VDSLR Lens Canon Fit is a wide-angle, fast aperture lens created for professional photographers & videographers. The lens features follow focus gearing & decoupled (de-clicked) apertures, which makes the lens suitable for video work. The Samyang 24mm T1.5 lens has the focusing distance & aperture settings clearly marked on the side of the lens barrel to allow quick & easy reference when mounted on a tripod. The stated aperture of T1.5 refers to the actual light transmission of the lens & is particularly important in the film industry where light readings are normally made manually. UMC stands for Ultra Multi Coated, which indicates that the lens has been covered with multi-layered, anti-reflective coating which minimises reflections & increases image contrast. This lens is a manual focus lens & does not have AF.
