The Rokinon 12mm F/2.0 CS lens in silver is a prime wide-angle lens designed for Sony E-Mount cameras with APS-C sensors. It offers a 35mm equivalent focal length of 18mm and a field of view of 98.9 degrees, making it ideal for architecture, interior, and landscape photography. The high aperture of F/2.0 allows for outstanding performance in low-light conditions. The optical design includes three ED (Extra Low Dispersion) elements and two aspherical lenses to reduce chromatic aberration and distortion for sharper, clearer images. A nano-coating system minimizes surface reflections, lens flares, and ghosting, enhancing light transmission and increasing contrast. The lens features a durable silver finish, measures approximately 69mm in diameter and 59mm in length, and weighs about 254g, making it particularly portable. It offers manual focus for precise control with a minimum focusing distance of 20cm and is compatible with various Sony E-Mount APS-C camera models. The package includes a front and rear lens cap, and filters with a thread diameter of 67mm can be used. Designed for adult photographers of all genders, it emphasizes reliability and optical performance without electronic interfaces, focusing on manual operation for creative flexibility in various shooting situations.
