Lens Overview — Cooke 300mm T2.3

The Cooke Anamorphic/i 300mm T2.3 is a manual-focus prime cinema lens designed for professional digital cinema and film production. Built around a PL Mount, it is engineered to cover Super 35 image formats, making it a natural fit for industry-standard cinema camera systems. The lens sits in the telephoto focal length range at a fixed 300mm, offering a maximum aperture of T2.3 — a bright stop for a telephoto of this reach, giving cinematographers meaningful creative latitude in low-light environments and for managing depth of field.

Classified as an anamorphic type lens, it pairs the telephoto reach with the distinctive visual characteristics that anamorphic optics are known for. At 9.3kg, this is a substantial piece of glass that reflects the build quality and optical complexity expected from a professional cinema lens of this caliber. Focus is fully manual, with no autofocus capability and no image stabilization, consistent with the workflows of dedicated cinema production.

As part of the Anamorphic/i series, it is positioned as a core tool for cinematographers working on high-end narrative, commercial, and feature film productions who require consistent, reliable telephoto coverage within a matched lens family.

Description — Cooke 300mm T2.3

The Cooke Anamorphic/i 300mm T2.3 is a prime cinema lens built for serious production work. Mounted via the industry-standard PL Mount, it targets the Cinema / Video camera ecosystem and covers the Super 35 image format. With a maximum aperture of T2.3, this telephoto prime offers a bright stop that supports controlled depth-of-field work even at long focal lengths.

As an Anamorphic type lens, it brings the visual qualities associated with that optical category to the telephoto end of a cinema lens package. Focus is manual, with no autofocus or image stabilization — workflow characteristics expected in professional cinema environments where dedicated focus pullers operate the lens independently from the camera operator. The lens weighs 9.3kg, a figure that underscores the optical and mechanical engineering involved and demands robust camera support and rigging.

For productions building out a matched anamorphic cinema lens package, this 300mm focal length provides a substantial telephoto option within the Cooke Anamorphic/i lineup.
