Cooke S4 FF / i T2.0 prime 18mm

The Cooke S4 FF/i 18mm T2.0 prime lens expands the renowned S4 series into wide-angle, full-frame cinematography. Delivering an expansive 102-degree diagonal field of view on full-frame sensors, it pairs an ultra-wide perspective with the classic Cooke Look: dimensional contrast, gentle optical clarity, subtle warmth, and organic skin tone rendering. Designed for professional production environments, this lens provides seamless color and character matching across the entire S4 FF/i family.

Optical Character and Low-Light Precision

Featuring a fast maximum aperture of T2.0, the lens excels in low ambient light while offering refined depth-of-field control. Its nine-blade iris with slightly rounded blades produces smooth, circular out-of-focus highlights and a gradual focus fall-off. With a minimum focus distance of just 300mm from the camera sensor, cinematographers can capture dramatic wide-angle close-ups with expressive background separation.

Cinema Mechanics and /i Technology Integration

Built for demanding set workflows, the lens features a precision mechanical assembly with 270 degrees of focus barrel rotation for accurate, repeatable pulls. Integrated Cooke /i Technology continuously outputs frame-accurate metadata, including focus, iris, inertial motion, and factory-calibrated shading and distortion parameters, streamlining visual effects and virtual production pipelines.

The lens features a standardized 87mm front diameter, measures 124mm from the front element to the PL mount, and weighs 1.8kg. Please note that this lens does not feature screw-in filter threads. The Cooke S4 FF/i series is available in PL or LPL mount options; the specific mount supplied with this SKU is unassigned.
