Capture more delicate and wider world with portable 12mm extra-wide-angle lens\n\n- Nano Coating System (NCS) of Samyang Optics\n- Glass aspherical(AS) and low dispersion(ED) lenses\n- Hybrid aspherical lens (H-ASP)\n- 6 aperture blades creating almost circle shape\n- Designed for mirrorless, available to APS-C\n\nIt is a extra-wide-angle manual focus lens designed for APS-C crop sensor mirrorless cameras. With low distortion and wide angle, photographers who want wide-angle photos such as landscape and architectural images can create satisfactory images. F2.0 is very bright so it captures clear and vivid images even under relatively dark environment.\n\nFor the first time in Samyang Optics history, the independent NCS(Nano Coating System) technology was used. It creates even lower reflection rate than the original UMC (Ultra Multi Coating) and higher contrast. Also, the light penetration rate is very high to minimize flare and ghost. Optical construction of Samyang 12mm F2.0 NCS CS features 12 lenses in 10 groups – among lenses, there are 1 glass aspherical lens(AS), 1 hybrid aspherical lens (H-ASP) and 1 low-dispersion lens (ED) to provide high image quality. H-ASP minimizes color aberration to realize exceptional image quality and high contrast for center and corner of image even when aperture is fully opened. ED lowers unnecessary light dispersion to drop color aberration effectively. With such optical construction, it has 0.2m of minimum focal length.\n\nThere are 6 aperture blades designed to be almost as a full circle when aperture is closed which expresses starlike ray clearly and beautifully in deep depth of field images. The frame of Samyang 12mm F2.0 NCS CS is compact and solid since it is made of high-strength aluminum alloy. Trustworthy images can be captured even under inferior environment. Also, petal-shaped lens hood to shelter lens from unnecessary light is provided.\n\nAvailable for 5 camera mounts: Canon-M, Sony-E, MFT, Samsung NX, and Fujifilm-X
