Sigma 20mm T1.5 FF High Speed Cine Prime

The 20mm is the wide end of our five-lens Sigma cine set and the lens we reach for when a shot needs to feel ambitious, environmental wides, interiors with foreground talent, dolly-in establishings. At T1.5 on a full-frame sensor, 20mm gives you something most rental houses can't: a wide angle of view with cinema-thin depth of field. Part of our matched five-lens Sigma FF High Speed Cine Prime set, 20, 24, 35, 50, 85mm, all PL mount, all T1.5, color-matched across the set, with a consistent 95mm front diameter so a single matte box configuration covers every focal length. These are rehoused versions of Sigma's Art series stills lenses in fully professional cinema housings, same optical formulas, same 50+ megapixel resolving power, in cine bodies with 180-degree focus throw, 0.8 MOD gear pitch, 9-blade rounded apertures, and proper hard stops. Built as one of the few cine sets that genuinely covers 6K-8K acquisition without revealing optical compromises. We run them primarily on the Alexa Mini LF (via our LPL-to-PL adapter) and the RED Komodo (via the Revolva PL-to-RF mount), and occasionally on the Tokina Cinema 25-75mm shots when a B-cam cine kit is needed.
