The Micro Four Thirds mount Rokinon 85mm T1.5 Cine AS IF UMC Lens is a prime telephoto lens designed for Micro Four Thirds cameras. Providing a 35mm-equivalent focal length of 170mm, this lens is well-suited to distant subjects, close-ups, and portraiture. Its fast T1.5 maximum aperture is further beneficial to working in low-light conditions and for greater control over selective focus and shallow depth of field effects.
One aspherical element has been incorporated into the optical design to minimize chromatic aberrations in order to produce sharper images. A UMC coating has also been applied to the lens elements to reduce surface reflections and prevent lens flare and ghosting for improved light transmission and more contrast-rich imagery.
