The enhanced 20mm T1.5 FF High-Speed Cine Prime from Sigma combines the same high-quality optics and mechanics of its FF prime line with a cine-oriented design including Cooke/i Technology that provides lens metadata to assist in post and visual effects production. This 20mm prime with PL mount is a wider focal length in the series offering full-frame sensor coverage, 6 to 8K resolution, lens markings in feet, and a T1.5 maximum aperture in a compact, lightweight form.
A common 95mm front diameter and similar physical attributes across the lens line makes it easier and quicker to mount lens accessories such as matte boxes, follow focuses, and lens control motors. The 9-bladed iris produces pleasing out-of-focus bokeh effects and ghosting and flaring have been minimized. Color reproduction is standardized for easier color correction. Each lens in the range offers consistent lens gear positions and 180° of focus barrel rotation. The FF High-Speed Cine Prime lenses also feature a clickless iris with linear markings, dampeners on each gear ring for silent operation, and industry-standard 0.8 MOD gear pitch.
