Cooke mini S4/i

The set includes the 18, 25, 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 cover Super35-sized sensors. The lenses feature Cam focus as opposed to Helicoid, which enables the focus mechanism to stay play and backlash free and require less service with normal use. 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 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.
