Rokinon Xeen 20mm T1.9 PL Mount Lensis built specifically for use as a cinema lens. It features an internal focus design so that the lens does not change size while focusing, this minimizes 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 20mm lens provides what is considered a wide angle of view on full-frame cameras, and a correspondingly tighter angle of view on smaller-format cameras.

The lens features dual sided focus scales marked in feet, with dual sided iris scales. The 11-bladed iris provides a rounded aperture for natural looking highlights and "bokeh" (out-of-focus highlights). The lens is a manual focus and iris lens, and does not have auto focus or auto iris capability. It incorporates cinema-style focus and iris gears that share the same position across the lenses in the Xeen set. The common 114mm front diameter allows for quick lens changes when using a matte box and focus accessories. The focus ring rotates 200° from close focus to infinity; this gives you a high degree of precision when adjusting focus. The lens mount can be shimmed, and additional mounts (available separately) may be used with the lens.

Dual right and left side focus and T-stop scales allow your focus puller to work from either side of the lens, without having to flip the lens in the mount, or facing upside numerals.

Each lens in the XEEN series share common focus and iris gear ring positions, which speeds up lens changes as accessories such as follow focus units or iris motors don't have to be re-positioned.

The common 114mm front diameter allows for quick lens changes since you don't have to swap out any donuts or adapters to use the same matte box.
