Cooke 5/i T1.4

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

Cooke /i Technology Lenses Electronics:
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.

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:
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.

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. (Except the 135mm)

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.

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

Reliability and Service:
Cooke 5/i prime lenses are designed to meet a market requirement for fully reliable performance with a minimum of downtime.
