The 180mm S4/i T2 Prime Lens from Cooke features optimal optical performance, /i Technology lens data transfer, and an ergonomic mechanical design with smooth, cam-based focus adjustments. This 180mm lens incorporates an aperture range of T2.0 to T22, focus scales marked in both feet and meters, and color matching with other modern Cooke cine-style lenses. The S4/i lenses minimize flare, distortion, veiling glare, and spherical aberrations even at the full aperture setting. The S4/i lenses are PL-mounted, making them compatible with most professional cine-style cameras.

Cooke's /i Technology provides a wealth of lens data crucial for matching shots, VFX work, and post-production. Metadata parameters include focal length, focus distance, lens aperture, depth of field, hyperfocal distance, the lens serial number, and more. A modular design ensures easier maintenance and servicing of the S4/i lens series.

Features

Optical Design

Maximum optical performance even at full aperture, with superior control of flare, distortion, and spherical aberration.

/i Technology

Contacts in the mount sync with /i compatible cameras and accessories, providing lens data including focusing distance, aperture, depth of field, hyperfocal distance, serial number, owner data, lens type, and focal length in both meters and feet.

Color Balance

All Cooke S4/i prime lenses are color balanced to match all modern Cooke lenses.

Aperture

Designed with a fast maximum T2.0 aperture and Super35 format coverage.

Index Marks

Every index mark is labeled, enabling more precise focus control.

Focus Movement

An award-winning cam-style focus movement is paired with a large lens barrel diameter, enabling smooth focus pulling with an increased number of focus markings, particularly at close focus. Spherical aberration has been controlled, eliminating compensation of changes in back focus with aperture, and a four-point contact bearing provides backlash-free movement.

Focus Scaling

Focus marks are engraved in large, clear numerals in feet on one side of the barrel and in meters on the other.

Compatibility

A front diameter of 136mm is compatible with select matte boxes and adapters.

Iris

An eight-blade linear iris provides an aperture range of T2.0 to T22.

Durable External Finish

A scratch-resistant, anodized finish provides a durable, hard-wearing surface to meet the most demanding environmental conditions.
