Features
Optical Design:
The optics are designed to give maximum performance at full aperture with superior control of flare, distortion and spherical aberration.
Color Balance:
All Cooke S4 prime lenses are color 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 labeled. More detailed markings allow for more detailed focus control.
Focus Movement:
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 anodized 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.
Reliability and Service:
The Cooke S4 prime lenses are designed to meet a market requirement for fully reliable performance with a minimum of downtime.
