The Sigma 40mm T1.5 FF High-Speed Cine Prime lens represents an advancement in optical and mechanical quality, characteristic of its full-frame prime series, while incorporating a cine-focused design. This design features Cooke /i Technology, which supplies lens metadata to facilitate post-production and visual effects processes. As a midrange focal length within the series, this 40mm prime lens, equipped with a PL mount, ensures full-frame sensor compatibility, supports resolutions of 6 to 8K, includes lens markings in feet, and boasts a T1.5 aperture, all within a compact and relatively lightweight structure.

The lens features a standard 95mm front diameter and shares similar physical characteristics with other lenses in the series, allowing for efficient and rapid attachment of accessories such as matte boxes, follow focuses, and lens control motors. Its 9-blade iris creates aesthetically pleasing out-of-focus bokeh, while minimizing ghosting and flaring. Color reproduction is consistent, simplifying the color correction process. Each lens in this collection maintains uniform gear positions and offers 180° of focus barrel rotation. Additionally, the FF High-Speed Cine Prime lenses are designed with a clickless iris featuring linear markings, dampeners on each gear ring for quiet operation, an industry-standard 0.8 MOD gear pitch, and engraved markings for enhanced durability.
