Cooke S4/i 300mm, T2.8 Prime Lens


Award-winning Cooke S4 Prime Lenses equipped with /i "Intelligent" Technology represent a major advance in fixed focal length lenses for 35mm format professional cinematography.

Cinematographers choose Cooke lenses for the "Cooke Look" - a sharp, subtle,
smooth rendering that provides dimensionality and high contrast, and pleases the eye.

"What is the Cooke Look? Cooke's have a shapeness, a presence to the image, a roundness, a feeling of giving depth and shape to the image. It's sharp edge-to-edge but the image has more presence -a depth and shape that's pleasing to the eye."
-Ed Lachman, ASC

Optical Design

The optics are designed to give maximum performance at full aperture with superior control of flare, distortion and spherical aberration.


/i Electronics

Accessible via cable connector near the lens mount and contacts in mount that sync with /i compatible cameras and accessories.


Color Balance

All Cooke 4/i prime lenses are colour balanced to a specification Cooke 5/i, miniS4/i, & Anamorphic/i.


Aperture

All Cooke S4/i 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.


Focus Illumination*

This revolutionary, 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.


Camera Mounts

Arriflex PL Mount with i/ Technology contact.


Focus

Large, clear numerals on both sides of the focus barrel benefit the focus puller when shooting under difficult lighting conditions.


Compatibility

All Cooke S4/i primes have a common fixed front diameter of 110mm (except for the 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.


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 eight-leaf linear module iris assembly is fitted into the Cooke S4/i primes with an aperture range of T2 to T22 (except 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 S4/i prime lenses are designed to meet a market requirement for fully reliable performance with a minimum of downtime.


/i Technology

All of our S4 Prime lenses (and CXX zoom lens) are supplied with /i Technology and are designed for  all PL mounted professional motion picture film and electronic cameras. The /i Technology provides cinematographers and camera operators with vital information on lens setting, focusing distance, aperture and depth-of-field, hyperfocal distance, serial number, owner data, lens type and focal length in both metric and footage measurements. For zoom lenses, the zoom position is displayed
