The 16mm f/2.0 ED AS UMC CS Lens for Samsung NX Mount from Bower is a manual focus wide-angle prime lens compatible with Samsung NX APS-C format mirrorless digital cameras. It provides a 79° angle of view which translates into a 35mm format focal length equivalency of 24mm. A fast maximum aperture of f/2.0 is effective in low light shooting and provides shallow depth of field. With two aspherical lens elements and high index extra-low dispersion glass, chromatic aberrations are minimized and sharp, color-accurate images are the result. Full multi-coating facilitates even light transmission and reduces ghosting and flares.
