Utilizing a multi-layer coating process for consistent color rendition from lens to lens, the Samyang 100mm T3.1 Cine DS Lens answers the challenge of assembling a set of lenses over time. Features industry standard geared focus and iris rings that share common position with other Rokinon Cine DS lenses. To aid focus pullers who have to work both sides of the lens, the aperture and focus scales are marked on both sides of the lens.This 100mm lens produces a 24.8 Degree angle-of-view when used with a full-frame sensor camera or a 35mm SLR. The 15 glass elements in 12 groups render sharply defined images with a minimum of distortion and chromatic aberrations, with a minimum focus distance of 1' from the lens. A removable lens hood provides flare protection when shooting without a matte box, and the lens's threaded front accepts 67mm filter rings.
