Rokinon's Xeen 135mm T2.2 Lens with Sony E-Mount is built specifically for use as a cinema lens. It features an internal focus design so that the lens does not change size while focusing, minimizing breathing. Each lens in the Rokinon Xeen cinema lens set is multi-coated for good contrast, glare prevention, and color matched to a factory standard, allowing you to assemble a set over time with minimal color shift. This 135mm focal length is often chosen for portraits and close-ups. The lens features dual-sided focus scales in feet, with dual-sided iris scales. The 11-bladed iris provides a round aperture for natural looking highlights and Bokeh.
