Cooke Anamorphic/i T2.3
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 cable connector near the lens mount and contacts in mount that sync with /i compatible cameras and accessories.
Colour Balance All Cooke Anamorphic/i prime lenses are colour balanced to a specification within parameters approved by Kodak and are colour-matched and compatible with Cooke 5/i, Cooke S4/i, miniS4/i, and CXX 15-40mm T2 S4/i Zoom lenses.
Aperture All Cooke Anamorphic/i primes have a true T2.3 aperture and cover Super 35mm format except the 65mm MACRO which has a T2.6 aperture.
Index Marks Every index mark is labeled. 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.
Focus Scaling Large, 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.
Camera Mounts Cooke Hardened PL Mount with /i Technology contacts.
Compatibility All Cooke Anamorphic/i lenses have a common, fixed front diameter of 110mm, except for the 25, 65 MACRO and 300mm focal lengths and the Anamorphic/i zoom lenses, which are 136mm. All have an iris drive gear of 134T 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 An eleven-leaf linear module iris assembly is fitted into Cooke Anamorphic/i primes with an aperture range of T2.3 to T22; T2.6 to T22 on the 65mm MACRO, T2.8 to T22 on the 180mm, and T3.5 to T22 on the 300mm.
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 Cooke Anamorphic/i prime lenses are designed to meet a market requirement for fully reliable performance with a minimum of downtime.”
The Anamorphic /i lenses offer superb optical and mechanical performance. Distortion, veiling glare, flares, and all aberrations are controlled at all apertures over the whole field of view. Like our S4/i, 5/i and miniS4/i prime lenses, the cam focus mechanism allows for smooth focus adjustments. Modular construction increases ease of maintenance and serviceability. The Anamorphic /i lenses are designed and made in Leicester, England.
