overview
Built for professional filmmaking, the Sigma 20mm T1.5 FF High-Speed Prime Lens offers fast exposure reading and accurate color rendering with Canon EF-mount cinema cameras. It has scale markings in feet for the focus and T-stop values. The 180° rotation for the focus ring allows you to shift the emphasis between two long-situated points. This Sigma cine lens has a 9-blade diaphragm that creates the cinematic out-of-focus background that every director requires. In addition, the T1.5 aperture opening ensures bright images in low-light conditions. With the cine-standard 0.8 Mod gears, the lens allows you to use various industry standard accessories such as a follow focus unit. Also, the dampener in the rings prevents metallic sounds when you turn them to the endpoint. The front 95mm diameter enables the use of various matte boxes. The lens sports an all-metal body with dust- and splash-proof sealing.
