The 16mm f/2.0 ED AS UMC CS Lens for Sony E Mount from Samyang is a manual focus wide-angle prime lens compatible with APS-C format mirrorless digital cameras. It provides an 83.1° angle of view which translates into a 35mm format 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 one extra-low dispersion element, chromatic aberrations are minimised and sharp, colour-accurate images are the result. UMC lens coating facilitates even light transmission and reduces ghosting and flares.
