Called the Cooke RED Set, the new digital-cinematography lenses incorporate metadata capture technology that can be read directly by the contacts of the RED camera lens mount. The Cooke RED Set includes: the S4/ 15-40mm, T2.0 CXX Zoom Lens; S4/ 50mm, T2.0 Prime Lens; S4/ 75mm, T2.0 Prime Lens; and S4/ 100mm, T2.0 Prime Lens."
