Lens Overview — Cooke 300mm T2.8

The Cooke 300mm S4/i is a manual-focus cinema prime lens built around a PL Mount and designed for Super 35 format camera systems. With a maximum aperture of T2.8, this telephoto prime sits comfortably in the Cooke S4/i line, offering a fixed 300mm focal length well suited to isolating subjects at distance on professional cine productions. Weighing 4.717kg, it is a substantial piece of glass that signals its place in high-end, set-built cinematography workflows rather than run-and-gun use.

The lens is fully manual focus, which is standard practice in cinema environments where a dedicated focus puller works from calibrated focus marks. The PL Mount is the industry-standard mount for professional cinema cameras, ensuring broad compatibility across the Cinema/Video camera ecosystem. The Super 35 format coverage makes it a natural match for the dominant sensor size found in digital cinema cameras.

Without image stabilization, the lens relies on the stability of the rig or support system, again consistent with professional production norms. For productions already working within the Cooke S4/i family, this 300mm prime extends telephoto reach while maintaining the consistent optical character and color rendering the S4/i series is known for across its focal length range.
