T1.4 Aperture
All Cooke 5/i primes have a true T1.4 aperture and cover Super 35mm format.

Index Marks
Every index mark is labeled. More detailed markings allow for more detailed focus control.

Focus Movement
Our 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
PL Mount

Focus Scaling
Large, clear numerals on both sides of the focus barrel benefit the focus puller when shooting under difficult lighting conditions. Plus the the Entrance Pupil position is engraved on the lens

Compatibility
All Cooke 5/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

A seven-leaf linear module iris assembly is fitted into the Cooke 5/i primes with an aperture range of T1.4 to T22.

Weight/Size Ratio
