Samyang's Xeen 35mm T1.5 Lens 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 the appearance of breathing when changing focus. Each lens in the set is multi-coated for good contrast, glare prevention, and color match to a factory standard, allowing you to assemble a set over time with minimal color shift. This 35mm lens provides what is considered a somewhat wide angle of view on full-frame cameras, and a tighter angle of view on smaller formats.
