Description — Cooke 21mm T2
The Cooke 21mm S4/i T2 Cine Lens is a manual focus prime designed specifically for Cinema/Video production, featuring a PL Mount and coverage for Super 35 sensor formats. With a maximum aperture of T2, this wide-angle prime offers solid low-light capability rated in true T-stop values, giving camera crews accurate exposure predictability across a matched set of lenses. The 21mm focal length places it firmly in wide-angle territory, suitable for expansive environmental shots, architectural interiors, and scenes requiring a broader field of view.
Weighing 2000g, the lens carries the kind of substantial mechanical presence that supports smooth operation with follow focus systems and cinema rigs. There is no image stabilization, consistent with professional cinema workflows where stabilization is managed externally. The PL Mount provides compatibility with a wide range of professional cinema cameras used across film and high-end television production.
As a fixed prime with no zoom function, it is purpose-built for productions prioritizing optical consistency and cinematic image quality at a specific focal length.
