The Nikon F mount Rokinon 10mm f/2.8 ED AS NCS CS Lens is a prime, manual focus wide-angle lens designed specifically for use with APS-C sized image sensors. Providing a 35mm-equivalent focal length of 15mm and a broad 109.5° 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.
The Nikon F mount of this lens incorporates a CPU that enables full control over exposure parameters, including P/A/S/M modes, with Nikon DSLRs.
