The Rokinon 12mm f/2.0 NCS CS Lens is a prime wide-angle lens designed specifically for use with APS-C sized image sensors. Providing a 35mm-equivalent focal length of 18mm and a broad 98.9° angle of view, this lens is well-suited for architectural, interior, and landscape images. Its fast f/2.0 maximum aperture is further beneficial to working in low-light conditions.
Three extra-low dispersion elements and two aspherical elements have been incorporated into the optical design to minimize chromatic aberrations and distortion in order to produce sharper images. Additionally, a Nano Coating System (NCS) has been applied to the lens elements in order to reduce surface reflections and prevent lens flare and ghosting for improved light transmission and more contrast-rich imagery.
