The black 12mm f/2.0 NCS CS Lens from Samyang is a wide-angle prime lens designed specifically for use with APS-C format image sensors. Providing a 35mm-equivalent focal length of 18mm and a broad 98.9° angle of view, this lens is well-suited for architectural, interior, and landscape images. Its fast f/2.0 maximum aperture is beneficial to working in low-light conditions. One aspherical element, one hybrid aspherical element and three elements made of low dispersion glass have been incorporated into the optical design to minimize chromatic aberrations and distortion for sharper, high contrast imaging throughout the frame.
