Lens Overview — Cooke 40mm T2.8

The Cooke 40mm T2.8 miniS4/i is a manual-focus prime cinema lens built around a PL Mount and designed to cover Super 35 sensors. With a maximum aperture of T2.8, it offers solid light-gathering capability suited to a wide range of production lighting environments. As a fixed 40mm focal length, it sits in the standard focal length range, making it a versatile choice for narrative cinematography, documentary work, and commercial productions where a natural perspective is valued.

The lens is calibrated in feet, which aligns with the conventions of many professional film sets, particularly those working within North American and international productions that use imperial measurement standards. Weighing 3.4kg, the miniS4/i is a substantive piece of glass that reflects the build quality expected from a professional cinema lens intended for demanding on-set use.
