The 25mm T2.8 miniS4/i Cine Coated Lens 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. These lightweight, cost-effective companions to Cooke's already established S4/i lenses 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, making up for light sensitivity with reduced size, weight, and cost.

This 25mm lens is a prime (no pun intended) example: its PL mount makes it compatible with the most commonly used professional digital cinema cameras, including the RED ONE, Sony F35, and Arri D21. Color-matched and interchangeable with all Cooke lenses, this lens 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 the perfect tool for multi-camera shoots, 2nd unit photography, stunt work or filmmakers 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 format.
Index Marks
Every index mark is labeled. More detailed markings allow for more detailed focus control.
Focus Movement
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.
Weight/Size Ratio
These lenses are designed for all shooting applications, including handheld and Steadicam, providing a comfortable balance ratio with the latest compact cameras.
Reliability & Service
Cooke miniS4/i prime lenses are designed to meet a market requirement for fully reliable performance with a minimum of downtime.
The lens features 3.4" (87mm) front diameter for attaching matte box, filter ring, and add-on lens accessories.
