Lens Overview — Cooke 40mm T2.0

The Cooke 40mm T2.0 S7/i Prime Lens is a full-frame cinema prime built for professional motion picture and digital cinema production. Mounted in the industry-standard PL Mount, it is designed to integrate seamlessly into high-end cinema camera setups that rely on the PL ecosystem. With a maximum aperture of T2.0, it offers solid low-light capability and a degree of background separation well-suited to narrative and documentary work.

The lens covers a full-frame sensor format, making it compatible with large-format cinema cameras operating at that sensor size. At 40mm, it sits in the standard focal length range, offering a perspective that tends to feel natural and unexaggerated — a practical choice for dialogue scenes, handheld work, and general coverage. Weighing 3,500g, this is a substantial lens built to cinema production standards, with the heft typically associated with high-quality cine glass.

Focus is entirely manual, which is standard practice in professional cinema environments where a dedicated focus puller manages critical focus throughout a shot. There is no image stabilization, consistent with the expectations of a cinema prime intended for use on stabilized rigs or gimbals.

Description — Cooke 40mm T2.0

The Cooke 40mm T2.0 S7/i Prime Lens is a professional cinema prime designed for full-frame sensor coverage and built around the PL Mount, placing it firmly in the world of high-end motion picture and digital cinema production. With a maximum aperture of T2.0, this lens delivers dependable performance in lower-light conditions while offering the background separation that cinematographers value in a fast prime. The 40mm focal length sits in the standard range, making it a go-to choice for scenes requiring a natural, undistorted perspective.

At 3,500g, this is a solidly constructed lens with the weight and build quality expected from a dedicated cinema optic. Focus is manual, which aligns with professional film production workflows where a focus puller operates the lens independently from the camera operator. The lens is categorized as a prime in the standard focal length range, and carries no image stabilization — standard for cinema primes used on professionally stabilized camera support systems.

The PL Mount ensures broad compatibility across cinema camera platforms that use this widely adopted standard.
