The Samyang 35mm f/1.4 AS UMC has been designed to work with reflex cameras of most well known brands, equipped with full-frame or APS-C sensors. Optical construction of the lens is based on 12 elements arranged in 10 groups. The lens comprises one aspherical lens element and two elements made of glass with a high refraction factor. High-quality multi-layered anti-reflection coatings ensure high contrast and accurate colour reproduction. The product is also fitted with the system of gliding lenses to maintain high image quality at the minimum focusing distance. Samyang 35mm f/1.4 AS UMC with Nikon F mount has been also fitted with an electronic circuit to control exposure parameters from the camera level and take full advantage of the i-TTL flash system. Thanks to the detailed parameters connected with the range of available apertures, focal length and focus confirmation, shooting with Samyang lens has never been so easy and comfortable. When attached to a full-frame camera, this lens becomes a bright, wide-angle lens ideal for landscape photography. The same product fitted on the APS-C camera turns into a 50-mm lens providing wide range of applications. In the Four Thirds system, Samyang 35 mm can be freely used as a portrait photography lens with the focal length equal to 70mm.
