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 the need to com-

pensate for changes in back focus with aperture. A four-point contact

bearing provides a smooth positive backlash-free movement.

Camera Mounts Cooke Hardened PL Mount with /i Technology

contact.

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.

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 lenses are designed to meet a

market requirement for fully reliable performance with a minimum

of downtime.

Optical Design The optics are designed to give maximum

performance at full aperture with superior control of flare, distortion

and aberration.

I Technology Accessible via contacts in the lens mount that

sync with /i compatible cameras. On the 5/i, S4/i, Anamorphic/i,

Panchro/i Classic and S7/i lenses, there is also a cable connector

near the lens mount.

Colour Balance All Cooke series of lenses are colour balanced,

color-matched and compatible with each other.

The Cooke Look

Of course.

Coverage All Cooke lenses cover the Super 35mm format.

Index Marks Every index mark is labelled. More detailed

markings allow for more detailed focus control.

Focus Scaling Large, clear numerals on both sides of the

focus barrel benefit the focus puller when shooting under difficult

lighting conditions.
