Shoot 35mm, Super 35mm, Full Frame and Beyond

The Cooke S7/i, T2.0 Full Frame Plus Primes are designed to cover the emergent full frame cinema camera sensors, up to the full sensor area of the RED Weapon 8K (46.31mm image circle). The S7/i enables you to shoot 35mm/Super 35mm format, and also to be prepared when camera sensors go to full frame, VistaVision and beyond.

Shoot 35mm / Super 35mm formats, full frame, VistaVision and beyond – all with The Cooke Look. The lenses have a common fixed front diameter of 110mm, with a focus drive gear of 140T x 0.8 mod and an iris drive gear of 134T x 0.8. A nine-leaf linear module iris assembly is fitted into the Cooke S7/i lenses. The average weight of an S7/i lens is approximately 3.5kg

Superb optical and mechanical performance, control of flare, distortion, veiling glare and spherical aberrations at full aperture. The cam-type focus mechanism allows for smooth focus adjustments. Modular construction increases ease of maintenance and serviceability.

The S7/i lenses come equipped with /i Technology for frame by frame digital information capture, as do all modern Cooke cine lenses for film and digital capture.



Key Features

Optical Design

The optics are designed to give maximum performance at full aperture with superior control of flare, distortion and spherical aberration.


Accessible via cable connector near the lens mount and contacts in mount that sync with /i compatible cameras and accessories.

Colour Balance

All Cooke 5/i prime lenses are colour balanced, colour-matched and compatible with Cooke S4/i, miniS4/i and Anamorphic/i.

T2.0 Aperture

Cooke S7/i Primes have a true T2.0 aperture and cover 35/Super 35mm, Full Frame and beyond.

Index Marks

Every index mark is labelled. More detailed markings allow for more detailed focus control.

Focus Movement

Cooke’s Academy Award winning cam-style focus movement coupled with the added benefit of a large lens barrel diameter, has allowed for an increased number of focus markings, particularly at close focus. Spherical aberration has been controlled throughout the range of focal lengths to eliminate compensation of changes in back focus with aperture. A four-point contact bearing provides a smooth positive backlash-free movement.

Focus Illumination

The 5/i’s patented, dimmable, illuminated focus ring has two separately toggled light pipes that allow the camera operator or focus puller to read the focus scale in low lighting conditions. Illumination options are controlled on the lens or via an external controller.

Camera Mounts

Cooke Hardened PL Mount with /i Technology contact.

Focus Scaling

Large, clear numerals on both sides of the focus barrel benefit the focus puller when shooting under difficult lighting conditions.


All Cooke S7/i Primes have a common fixed front diameter of 110mm, with a focus drive gear of 140T x 0.8 mod and an iris drive gear of 134T x 0.8.

External Finish

A scratch resistant PTFE hard anodised finish is provided on all Cooke lenses, providing a durable, hard-wearing surface to meet the most demanding environmental conditions.


A nine-leaf linear module iris assembly is fitted into the Cooke S7/i Primes.

Weight/Size Ratio

The lenses are designed for all shooting applications, including handheld and Steadicam, providing comfortable balance ratio with the latest compact cameras.
