The Rokinon 85mm T1.5 Cine Lens produces a slightly telephoto angle-of-view on full-frame sensors. It features a very fast maximum aperture of T1.5 and an 8 blade iris, for shallow depth of field with attractive bokeh. The focus and aperture control rings are outfitted with industry standard gearing, which provides an interface for working with a traditional follow focus. The aperture control ring has also been "declicked", which facilitates smooth iris pulls. This 85mm Cine Lens is for use with Canon EF cameras.
