The 14mm f/2.8 ED AS IF UMC Lens from Samyang is a manual focus, manual aperture, ultra-wide angle prime lens compatible with APS-C format mirrorless digital cameras. It provides a 93.9° angle of view which translates into a 35mm format focal length equivalency of 21mm. A maximum aperture of f/2.8 is effective in low light shooting and provides shallow depth of field. With extra-low dispersion, aspherical and hybrid aspherical lens elements, chromatic aberrations are minimized and sharp, color-accurate images are the result. UMC lens coating facilitates even light transmission and reduces ghosting and flare. The minimum focus distance for this lens is 11".
