Beautiful, bright lenses that have a great build quality.

Experience the unparalleled performance of the 20mm T1.5 FF Fully Luminous High-Speed Prime Cine Lens for PL Mount, a compact yet powerful lens designed for professional cinematography. This lens is engineered to deliver stunning image quality, rivaling high-end prime lenses, while providing full-frame coverage.

Designed for 6K-8K shooting, this lens takes cinematography to the next level, allowing for filming of various cuts without the need for lighting adjustments. Each lens undergoes rigorous inspection to ensure compliance with all specifications, using Sigma's proprietary A1 Modulation Transfer Function (MTF) measuring system. This system uses 46-megapixel Foveon direct image sensors to detect even the most minute high-frequency details, ensuring high-performance shooting.

This lens also minimizes flare and ghosting through computer-based ray tracing from the design stage, enhancing contrast in backlit conditions. It delivers sharpness combined with an outstanding bokeh effect, meeting the high demands for image quality in both still photography and cinematography.

The lens features 6K-8K class resolution, making it ideal for high-resolution shooting and chroma keying. It also complies with Sigma's CCI standard, ensuring standardized color balance across the lineup for easy color correction.

Built to last, the lens boasts a 100% metal body, dust-proof and splash-proof construction, and laser engraving for enhanced durability. It features luminous paint for enhanced visibility in low light conditions, and a front diameter of 95mm, compatible with matte boxes.

The lens also offers standardized gear positions, a silent ring stopper, and a 180-degree focus rotational angle for high-precision focusing. The iris ring offers smooth, manual control without clicks, and the T-stop display contributes to high-precision exposures.

The mount with electronic contacts allows the lens to communicate important information to the camera body, and the lens comes with a dedicated lens support foot to minimize load on the camera body while enhancing mount stability.

Experience the combination of performance and compact design at its finest with the 20mm T1.5 FF Fully Luminous High-Speed Prime Cine Lens for PL Mount.
