Colour-matched and compatible with our Mini S4/i’s, and Cooke Anamorphics, S4/i’s deliver a true T2 open aperture on all primes as well as one of the closest minimum focus capabilities available. S4/i's are loved for their warmth and gentle focus falloff, commonly known as the "Cooke Look". These lenses have superb optical and mechanical performance, they veil glare and spherical aberrations at full aperture, and their cam-type focus mechanism allows for smooth focus adjustments. The S4/i Data technology provide vital metadata about lens setting, for focus pullers, post production and VFX work.
