The Samyang 16mm T2.2 ED AS UMC CS Video with Micro Four Thirds fit is a wide-angle, bright cine lens with geared, manual focus & aperture control rings optimised for cinematography. The aperture ring is also stepless for smooth iris pulls, & depth-of-field markings on the side of the lens provide an essential assistance to focus pullers. This lens has a maximum aperture of T2.2 which refers to the actual light transmission of the lens & is particularly important in the film industry where light readings are normally made manually.
