20 mm Sigma FF High-Speed Art Prime Lens T1.5

The enhanced 20mm T1.5 FF High-Speed Art Prime 2 Lens from Sigma combines the same high-quality optics and mechanics of its FF prime line with a cine-oriented design, and it now utilizes Cooke /i Technology that provides lens metadata to assist in post and visual effects production. This 20mm PL mount prime is a wide focal length in the series, offering full-frame sensor coverage, 6 to 8K resolution, lens markings in meters, and a T1.5 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 Art Prime 2 lenses also feature a clickless iris with linear markings, dampeners on each gear ring for silent operation, industry-standard 0.8 MOD gear pitch, and engraved markings for durability.
