Optical Design   The optics are designed to give maximum performance at full aperture with superior control of flare, distortion and spherical aberration.
/i Electronics    The S4/i system is designed for use with LDS equipped cameras and for use with any professional film camera -- 16mm or 35mm -- using a /i Lens Display unit, provided by Cinematography Electronics. All new Cooke S4 lenses incorporate /i technology.
/i dataLink to save considerable time and money in post.
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, 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.
