Cooke 5/i Prime Lenses, T 1.4 - 18, 25, 32, 40, 50, 65, 75, 100, 135

See in the dark -- with T1.4 speed and a focus ring that illuminates when you need it. External lamps are no longer necessary for the focus puller to see in the dark because this new design incorporates a simple on/off and dimmer to adjust the level of illumination desired on the aperture ring. You now have the visability you need without affecting the light coming into the camera.

Cooke 5/i 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.

Cooke 5/i Prime Lenses were designed and developed in close technical collaboration with industry professionals. They are colour-matched and compatible with Cooke S4/i, Panchro by Cooke, CXX 15-40 mm T2 S4/i Zoom, 18-100mm T3.0 and 25-250mm T3.7 and the SK4 16mm lenses.

Cooke S4/i Prime Lenses - True T2 Prime Lenses  - 12, 14, 16, 18, 21, 25, 27, 32, 35, 40, 50, 65, 65SF**,75, 75SF**,100, 135, 150, 180 and 300mm

The Cooke S4 Prime Lenses were designed and developed in close technical collaboration with Clairmont Camera and Otto Nemenz in Hollywood. They are colour-matched and compatible with Cooke's 18-100mm T3.0 and 25-250mm T3.7 zoom lenses. The S4 lenses represent a major advance in fixed focal length lenses for 35mm format professional cinematography. 1998 - Cinec Award for Technical Excellence, Germany 1999 - Academy of Motion Picture Arts and Sciences Scientific and Engineering Award for Optical and Mechanical Design 2000 - Primetime Emmy Award for Outstanding Achievement in Engineering Development 2001 - Two Queen's Awards for Enterprise - International Trade and Innovation, England 2001 - Winner, Exporter of the Year, 2001 International Business Award, Export Times and Trade Partners UK 2001 - Winner, Product Innovation, 2001 International Business Award, Export Times and Trade Partners UK Cooke S4/i Telephotos * As of February 2005 all new S4 lenses incorporate /i technology **65SF Soft Focus Attachment 65SF is a soft-focus attachment for the 65mm focal length and for the 75mm focal length via a Cooke 75mm adapter ring. The design for the attachment is based on Cooke's PS945 soft focus lens for 4x5 large format photography. See the effect in sample photos taken with the PS945 lens. The effect is high resolution with a stunning glow to the highlights -- subtle, but most pronounced wide open at T2, becoming less pronounced as you stop down. (Effect from T2 to T4 with the 65mm lens; T2 to T5.6 with the 75mm lens.) More details. 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. Reliability and Service The Cooke S4 prime lenses are designed to meet a market requirement for fully reliable performance with a minimum of downtime.
