Lens Overview — Cooke 300mm T3.3 Prime

The Cooke S7/i 300mm T3.3 is a prime cinema lens built for full frame coverage, making it a strong choice for productions shooting on large-format cinema sensors. With a fixed focal length of 300mm and a maximum aperture of T3.3, this telephoto prime is designed for cinematographers who need reach without sacrificing too much light gathering capability. The lens is manually focused, which is standard practice in professional cinema workflows where focus pullers work with calibrated barrel markings and follow focus systems.

Mounted via PL Mount, it integrates seamlessly into established cinema camera rigs and follow focus setups. The lens is classified as a full frame optic, meaning it is engineered to cover larger sensor formats common in modern high-end digital cinema cameras. Weighing in at 4.4kg, this is a substantial piece of glass that will require proper lens support and rigging on set.

There is no image stabilization, which is typical for cinema prime lenses used on stabilized rigs or dollies. The Cine type classification confirms it is built to professional cinema standards with geared focus and aperture rings suited for on-set operation.
