The Micro Four Thirds mount Rokinon 10mm f/2.8 ED AS NCS CS Lens is a prime wide-angle lens designed specifically for use with Micro Four Thirds sized image sensors. Providing a 35mm-equivalent focal length of 20mm and a broad 93.4° angle of view, this lens is ideally suited for interior, architectural, and landscape photography applications. One extra-low dispersion element 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.
