It 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 satisfactory images. F2.0 is very bright so it captures clear and vivid images even in a relatively dark environment.

For the first time in Samyang Optics history, the independent NCS(Nano Coating System) technology was used. It creates an 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 ghosts. 

The optical construction of Samyang 12mm F2.0 NCS CS features 12 lenses in 10 groups – among lenses, there is 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 colour aberration to realize exceptional image quality and high contrast for the centre and corner of the image even when the 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 the aperture is closed which expresses starlike rays 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 aluminium alloy. Trustworthy images can be captured even in an inferior environment.

Nano Coating System (NCS) of Samyang Optics
For the first time in Samyang Optics history, NCS (Nano Coating System) is used to lower reflection rates more effectively to provide higher contrast.

Low dispersion lens (ED)
It lowers unnecessary light dispersion to effectively drop colour aberration.

Glass aspherical lens (AS)
It minimizes colour aberration to realize exceptional image quality and high contrast for the centre and corner of the image even when the aperture is fully opened. 

Aperture closed to circle shape
6 aperture blades create almost a full circle when closed and express rays beautifully as starlight.
