S4Cooke /i Technology Lenses Prime Main Features
Optical DesignThe optics are designed to give maximum performance at full aperture with superior control of flare, distortion and spherical aberration.
Cooke /i Technology Lenses ElectronicsAccessible via contacts in PL mount that sync with /i compatible cameras.
Colour BalanceAll S4/i prime lenses are colour balanced, color-matched and compatible with Cooke 5/i, miniS4/i and Anamorphic/i.
ApertureAll S4/i primes have a true T2 aperture and cover Super 35mm format, apart from the 300mm (2.8).
Index MarksEvery index mark is labelled. More detailed markings allow for more detailed focus control.
Focus MovementOur 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 MountsCooke Hardened PL Mount with /i Technology contacts.
Focus ScalingLarge, 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.
CompatibilityAll Cooke S4/i 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

IrisAn eight-leaf linear module iris assembly is fitted into S4/i primes with an aperture range of T2 to T22.(Except 300mm)
Weight/Size RatioThe lenses are designed for all shooting applications, including handheld and Steadicam, providing comfortable balance ratio with the latest compact cameras.
