The Samyang 12mm F2.0 NCS CS Camera Lens is an 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 amazing images. F2.0 is very bright so it captures clear and vivid images even in relatively dark environments. 

For 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 minimise 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 minimises colour aberration to realise exceptional image quality and high contrast for centre and corner of image even when aperture is fully opened. ED lowers unnecessary light dispersion to drop colour aberration effectively. With such optical construction, it has 0.2m of minimum focal length. 

There 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 Camera Lens is compact and solid since it is made of high-strength aluminium alloy. Trustworthy images can be captured even under inferior environment. The petal-shaped lens hood will shelter the lens from unnecessary light.
