The set of six includes the 18, 21, 32, 50, 75,  and 100mm lenses. Each lens in the set features a clickless aperture with a T-stop range of 2.8 to 22, and they cover Super35-sized sensors. Featuring a PL mount, these lenses are designed as true cinema lenses with geared focus and iris, as well as manual focus.
The lenses are color matched to a factory standard, and they share similar gear positions making for fast lens changes. All the lenses except for the 18mm feature an 87mm front diameter, again for fast lens changes, with the 18mm featuring a 110mm front diameter. Cooke's /i technology system shares lens information with your camera, providing the camera is /i compatible. This set of lenses is marked in feet and inches.
