The Samyang 12 mm offers an equivalent wide angle of 18mm on APS-C sized sensors, 24mm on Micro Four Thirds (MFT) mount. A fast aperture of f/2.0 allows shooting even in lower light conditions. Optical construction of the lens comprises 12 elements divided into 10 groups including one aspherical lens (ASP) and one hybrid aspherical lens (H-ASP). There are also three lenses made of ED glass, offering superb performance. Technologically the Samyang 12mm lens is the most advanced Samyang lens to date.
The Samyang 12mm features Samyangs new nano crystal anti-reflection coating system (NCS). These new coating provides even lower reflection factor than Samyang's UMC coatings. The NCS coating technology offers exacting process to apply anti-reflection coating more evenly on the surface of the lens. Other benefits brought by the nano crystal layer include improved light transmission, increased resistance to reflections resulting in maximum image contrast. This is applied to 2 elements in the 12mm lens.
