It is also available for cameras with Micro Four Thirds mount (Olympus and Panasonic). Samyang 16mm f / 2.0 ED AS UMC CS has manual focusing with a wide, ribbed and smooth focus ring. Its advanced optical design consists of 13 elements divided into 11 groups, including two aspherical elements and a hybrid-aspheric element to give maximum sharpness all the way to the edges.
