ABOUT THIS PRODUCT


Award winning Cooke S4 Prime Lenses were designed and developed in close technical collaboration with industry professionals. They are colour-matched and compatible with Cooke's, 18-100mm T3.0 and 25-250mm T3.7, 15-40mm, T2.0 CXX zoom lenses and the SK4 16mm lenses.

Cooke S4 optics offer 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.

/i Technology
All of our S4 Prime lenses (and CXX zoom lens) are now supplied equipped with /i Technology, as of February 2005. S4/i lenses are designed for all PL mounted professional motion picture film and electronic cameras. The /i Technology provides cinematographers and camera operators with vital information on lens setting, focusing distance, aperture and depth-of-field, hyperfocal distance, serial number, owner data, lens type and focal length in both metric and footage measurements. For zoom lenses, the zoom position is displayed.

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

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

Colour Balance
All Cooke S4 prime lenses are colour balanced to a specification within parameters approved by Kodak.

T2 Aperture
All Cooke S4 primes have a true T2 aperture and cover Super 35mm format.

Index Marks
Every index mark is labelled. 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.

Camera Mounts
Arriflex PL Mount

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 S4 primes have a common fixed front diameter of 110mm, (except for 12mm, 150mm, 180mm, 300mm) with a focus drive gear of 140T x 0.8 mod and an iris drive gear of 114T 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.

Iris
A new eight-leaf linear module iris assembly is fitted into the Cooke S4 primes with an aperture range of T2 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.
