Cooke mini S4/i

18mm, 25mm, 32mm, 50mm, 75mm, 100mm.

This is a set of six lenses that cover the entire range of Cooke miniS4/i lenses. The set includes the 18, 25, 32, 50, 75, and 100mm lenses. Each lens in the set features a clickless aperture with a T-stop range of 2.8 to 22, and they cover Super35-sized sensors. The lenses feature Cam focus as opposed to Helicoid, enables the focus mechanism to stay play and backlash free and require less service with normal use. Featuring a PL mount, these lenses are designed as true cinema lenses with geared focus and iris, as well as manual focus.
The lenses are color matched to a factory standard, and they share similar gear positions making for fast lens changes. All the lenses except for the 18mm feature an 87mm front diameter, again for fast lens changes, with the 18mm featuring a 110mm front diameter. Cooke's /i technology system shares lens information with your camera, providing the camera is /i compatible. This set of lenses is marked in feet and inches.

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 contacts in PL mount that sync with /i compatible cameras.

 

Colour Balance

All miniS4/i prime lenses are colour balanced, colormatched and compatible with Cooke 5/i, S4/i and Anamorphic/i.

Compatibility

All Cooke miniS4/i primes, except the 18mm, have a common fixed 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.

Aperture

All miniS4/i primes have a true T2.8 aperture and cover Super 35mm format.

Camera Mounts

Cooke Hardened PL Mount with /i Technology contact.

 

Index Marks

Every index mark is labelled. More detailed markings allow for more detailed focus control

 

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.

.

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.

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

miniS4/i prime lenses are designed to meet a market requirement for fully reliable performance with a minimum of downtime.
