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.
• Optical Design: The optics are designed to give maximum performance at full aperture with superior control of flare, distortion and spherical aberration.
• Electronics: Accessible via contacts in PL mount that sync with /i compatible cameras.
• Colour Balance: All miniS4/i prime lenses are colour balanced to a specification within parameters approved by Kodak.
• Aperture: All miniS4/i primes have a true T2.8 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.
