About Rokinon 12mm F/2.0 Mirrorless

Release of Rokinon 12 mm 1:2.0 NCS CS will fill in the market gap in terms of lenses intended for APS-C mirrorless cameras with such a large angle of view and brightness. The lens has been designed for cameras fitted with a high resolution sensor (above 24 mln pixels). Rokinon Optics company has accustomed its clients to great quality optics offered at affordable prices. And this is also the case with 12 mm 1:2.0 NCS CS lens which provides technical parameters and potential that can easily compete with the best wide-angle prime and zoom lenses available on the market.

Rokinon 12 mm 1:2.0 NCS CS gives wide angle of view amounting to 98.9 degree and rectilinear image mapping function. Owing to a large aperture range of f/2.0, the lens can be a useful shooting device and offer high image quality even in poor lightning conditions. Optical construction of the lens comprises 12 elements divided into 10 groups, these components include one aspherical lens (ASP) and one hybrid aspherical lens (H-ASP). There are also three lenses made of ED glass with extremely low dispersion factor. Technologically, 12 mm NCS CS lens is the most advanced device branded with Rokinon logo.

Rokinon 12 mm 1:2.0 NCS CS is another (alongside with Rokinon 10 mm) lens with nanocrystal anti-reflective coating applied. This time, however, the NCS coating covers two lens elements. This type of coating gives smaller reflection factor than (U)MC layers and ideally sits on the lens element's surface due to the very application process. Benefits of using the nanocrystal cover, include: much better light transmission, higher resistance to reflections and higher contrast, which adds to optical resolution of the lens.

Rokinon 12mm 1:2.0 NCS CS is a perfect lens for landscape photography and can be useful in interior and architecture photography or astrophotography. The product comes with a removable lens hood and 67 mm filter mount. Its light weight (245 g) and compact shapes make it a perfect solution for mirrorless cameras of smaller sizes. After you connect it to a camera with APS-C sensor its field of vision will correspond to the small image lens with the focal length of 18 mm. Thanks to this feature combined with the aperture of 2.0, the lens is a perfect addition to non-full frame cameras.

Rokinon 12mm F/2.0 Mirrorless Reviews

Reviewed by 2 customers


Good all around wide


from Eugene, OR

The 12mm gives a very good wide shot without fisheye distortion. Very sharp corner to corner from F2.8 on. F2.0 is very good, completely usable. The manual focus wheel is just a tad stiff for my liking, but not bad at all. Build quality is very good. Would love to have a rubber grip on focus, but for this price I can't complain about the sturdy plastic ring. For a fairly cheap, relatively fast, wide angle, this lens gets the job done!

Great lens for the price


from Orange County, CA

Low distortion, sharp from about f2.8 and on. Manual focus and aperture. Compact design, some CA but manageable.
