Cooke S4 FF / i T2.0 prime 25mm

The Cooke S4 FF/i 25mm T2.0 prime lens brings the celebrated Cooke Look to large-format cinematography. Designed for full-frame sensor coverage, this high-performance wide-angle prime delivers gentle optical clarity, subtle warmth, natural skin tone reproduction, and smooth dimensional contrast across the entire frame.

Wide-Angle Perspective with Close-Focus Precision

With an expansive 84° full-frame diagonal angle of view (65° in Super 35), the 25mm prime captures expansive vistas and immersive interiors without harsh geometric distortion. A fast maximum aperture of T2.0 paired with a nine-blade, slightly rounded iris ensures smooth bokeh and natural focus roll-off. With a minimum focus distance of just 280mm from the sensor, cinematographers can shoot dramatic close-up compositions in tight production environments.

Cooke /i Technology and Mechanical Reliability

Engineered for professional production workflows, the lens features a precision-machined focus ring with 270° of smooth rotation for accurate focus pulling. Built-in Cooke /i Technology transmits frame-accurate lens metadata to compatible camera systems and post-production software, recording focus distance, iris position, inertial motion, and factory-calibrated optical shading and distortion tables.

Build Quality and Mount Options

The lens features a robust cine housing with an industry-standard 87mm front diameter, making it fully compatible with standard matte boxes and accessories. It also includes an M82 x 0.75 screw-in front filter thread. The lens measures 110mm from front to mount and weighs approximately 1.65kg. S4 FF/i lenses are produced in both PL and LPL mounts; note that the specific mount supplied with this SKU is not specified.
