The Rokinon 85mm T1.5 Cine Lens for Sony A 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.
The 85mm has a minimum focus distance of 3.6'. Internal focusing minimizes the effects of lens breathing, which insures a more consistent angle-of-view when adjusting focus. The lens is composed of 9 elements in 7 groups, including one aspherical element to reduce spherical aberrations. In addition, multi-coated elements help improve light transmission.
