Presenting the award-winning Cooke S4/i Prime Lenses series, innovatively designed through close collaboration with industry professionals. These lenses effortlessly deliver superior optical and mechanical performance, effectively controlling flare, distortion, veiling glare, and spherical aberrations even when wide open.
The S4 complete lens kit covers a focal range that goes from the 12mm lens to the 300mm. All of these lenses have a constant T2 max. iris aperture, excluding the 300mm (which is T2.8).
The whole set has a 110mm front diameter, so 4x5'6 matte boxes and filters are required to avoid vignetting. These lenses weigh from 1.5 to 4.7kg, and are only available in PL mount.
