Technical Documentation
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, the
180mm has a T2.8 aperture, and the 300mm has a T3.5 aperture.
Compatibility With the exception of the 25, 65 MACRO and 300mm lenses, all Cooke Anamorphic/i prime lenses have a common fi xed 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. The 25, 65 MACRO and 300mm Cooke Anamorphic/i primes have a
front diameter of 136mm.
Iris An eleven-leaf linear module iris assembly is fi tted 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.
T2.2 Aperture All Cooke Panchro/i Classic Primes have a true T2.2 aperture except the 18mm, 100mm (T2.6) and 152mm and cover Super 35mm format
Compatibility All Cooke Panchro/i Classic 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 134T x 0.8.
Iris A nine-leaf linear module iris assembly is fitted into the Cooke Panchro/i Classic Primes.
T2 Aperture All Cooke S7/i Primes have a true T2.0 aperture and cover 35/Super 35mm, Full Frame and beyond.
Compatibility All Cooke S7/i 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 134T x 0.8.
Iris A nine-leaf linear module iris assembly is fitted into the Cooke S7/i Primes.
T1.4 Aperture All Cooke 5/i primes have a true T1.4 aperture and cover Super 35mm format.
Focus Illumination The patented, dimmable, illuminated focus ring has two separately toggled light pipes that allow the camera operator or focus puller to read the
focus scale in low lighting conditions. Illumination options are controlled on the lens or via an external controller.
Compatibility All Cooke 5/i prime lenses have a common fi xed front diameter of 110mm, with a focus drive gear of 140T x 0.8 mod and an iris drive gear of
134T x 0.8. (Except the 135mm 5/i lens.)
Iris A seven-leaf linear module iris assembly is fi tted into Cooke 5/i primes with an aperture range of T1.4 to T22.
T2 Aperture All Cooke S4/i Primes have a true T2 aperture and cover Super 35mm format.*
*Apart from the 300mm (2.8)
Compatibility All 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 134T x 0.8.
Iris An eight-leaf linear module iris assembly is fitted into the Cooke S4/i Primes with an aperture range of T2 to T22. (Except 300mm)
T2.8 Aperture All miniS4/i primes have a true T2.8 aperture and cover Super 35mm format.
Compatibility All Cooke miniS4/i primes, except 18mm, have a common fi xed front diameter of 87mm, with a focus drive gear of 121T x 0.8 mod and an iris drive
gear of 119T x 0.8.
