ROKINON XEEN 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; this minimizes the appearance of breathing when changing focus. Each lens in the set is multi-coated for good contrast and glare prevention and is color-matched to a factory standard, allowing you to assemble a set over time with minimal color shift.
The lens features dual-sided focus scales marked on the feet, with dual-sided iris scales. The 11-bladed iris provides a rounded aperture for a natural-looking highlight and Bokeh. 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 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.
