Sigma High-Speed 20mm T1.5

Sigma High-Speed 20mm T1.5

The Sigma Cine 20mm T1.5 is a wide-angle prime that offers a strong sense of space while maintaining natural proportions, making it an excellent choice for interiors, ensemble blocking, gimbal/steadicam work, and narrative scenes that benefit from environmental context. The fast T1.5 aperture supports low-light shooting and provides meaningful depth separation even at a wide focal length, allowing subjects to stand forward in the frame without distorting the surrounding environment. On full-frame cinema sensors, the 20mm delivers an immersive look that feels expansive yet controlled.

Optically, the 20mm offers high resolution, natural contrast, and minimal chromatic aberration for clean, consistent image quality across the frame. Mechanically, it adheres to the Sigma Cine family’s unified design with a 95 mm front diameter, standardized gear placement across focal lengths, and a smooth 180° focus rotation for precise and repeatable pulls. It is available in ARRI PL, Canon EF, and Sony E mounts, each supporting their respective metadata communication protocols for integrated on-set and post-production workflows. Durable all-metal construction ensures reliability in professional production environments, making the 20mm T1.5 a versatile and cinematic wide-angle anchor within the Sigma Cine lineup.
