The Samyang 85mm T1.5 Cine Aspherical Lens for Canon EF features a "De-clicked" Aperture to reduce any noise and jerking sound while shooting. This lens is follow-focus compatible to provide a convenient, quick and precise method for controlling the focus on the camera without the need to constantly reach over to the front of the lens. The 85mm T1.5 Cine Lens is best used for shooting video.
The Samyang 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.
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, a multi-coated elements help improve light transmission.
