The Cooke 18mm T2.0 S7/i Full Frame Plus Prime Lens is designed to cover full frame cinema camera sensors up to at least the full sensor area of the RED Weapon 8K (46.31mm image circle). It is color-matched to other Cooke lenses to keep that well-known Cooke look, and has focus markings on both sides of the lens. A cam-type focus mechanism with a large lens barrel diameter and 270° of rotation from end-stop to end-stop allows for precision focus markings, especially at close focus.
The lens features a PL mount, which makes it compatible with most commonly used professional motion picture film and electronic cameras, and has an aperture range of T2.0 to T22. The PL mount incorporates i/Technology contacts that feed lens information metadata to a compatible camera, including focus distance, aperture and depth-of-field.
