The miniS4/i Cine Lens Set from Cooke comes with an illustrious heritage: most Hollywood films made in the first half of the 20th century were shot with Cooke lenses. Now, Cooke has revived the brand with a new set of lenses that further extend the company’s reputation for quality into the digital era. Comprising 18mm, 25mm, 32mm, 50mm, 75mm, and 100mm lenses, this set of lightweight, cost-effective primes are companions to Cooke’s already established S4/i lenses. They carry over the most desirable features of their more expensive brethren, sacrificing only a single T-stop in the process. And yet with their aperture range of T2.8 to T22, the miniS4/i remain extremely flexible and make up for light sensitivity with reduced size, weight, and cost.

Their PL mounts make the lenses compatible with the most commonly used professional digital cinema cameras, including the RED ONE, Sony F35 and F3, Canon C300 PL, and Arri D21. Color-matched and interchangeable with all Cooke lenses, this set combines classic, hand-fitted construction with a linear iris, cam-style focus, and /i Technology – which provides EXIF-like data to camera operators, cinematographers, and post-production technicians requiring precise measurements of lens and camera settings.

Cooke miniS4/i optics, meanwhile, are beyond superb, controlling flare, distortion, veiling glare, and spherical aberrations with the aperture wide open. This combination of unmatched image quality, state-of-the-art technology, and cost-effective durability makes this lens set the perfect tool for multi-camera shoots, second-unit photography, stunt work, or filmmaking on a budget.

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

/i Electronics
A cable connector near the lens mount and contacts in the mount sync with /i-compatible cameras and accessories

Color Balance
All Cooke miniS4/i prime lenses are color-balanced to a specification within parameters approved by Kodak

All Cooke miniS4/i primes have a true T2.8 aperture and cover Super 35mm-sized formats

Index Marks
Every index mark is labeled. More detailed markings allow for more detailed focus control

Focus Movement
The 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 Scaling
Large, clear numerals on both sides of the focus barrel benefit the focus puller when shooting under difficult lighting conditions

All Cooke miniS4/i primes 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

External Finish
A scratch-resistant PTFE hard-anodized finish is provided on all Cooke lenses, providing a durable, hard-wearing surface to meet the most demanding environmental conditions

An eight-leaf linear module iris assembly is fitted into miniS4/i primes, with an aperture range of T2.8 to T22
