Cooke miniS4/i Uncoated Elements for those who want a softer contrast, more flaring and an “older” lens look and feel. Cooke miniS4/i lenses are now available with uncoated front and/or rear elements. Uncoated elements may help create a different “historic look” – more flare, softer edges, etc. Footage showing the effect of coated vs. uncoated elements on the miniS4/i

Technical Specifications
Optical Design
The optics are designed to give maximum performance at full aperture with superior control of flare, distortion and spherical aberration.
Cooke /i Technology Lenses Electronics
Accessible via contacts in PL mount that sync with /i compatible cameras.
Colour Balance
All miniS4/i prime lenses are colour balanced, color matched and compatible with Cooke 5/i, S4/i and Anamorphic/i.
Aperture
All miniS4/i primes have a true T2.8 aperture and cover Super 35mm format.
Index Marks
Every index mark is labelled. More detailed markings allow for more detailed focus control.
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.
Camera Mounts
Cooke Hardened PL Mount with /i Technology contact.
Focus Scaling
Large, clear numerals on both sides of the focus barrel benefit the focus puller when shooting under difficult lighting conditions.
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.
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.
Iris
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
The lenses are designed for all shooting applications, including handheld and Steadicam, providing comfortable balance ratio with the latest compact cameras.
Included
Cooke Mini S4i 8 Lens Set PL mount is avalable to rent at FRENEL rental.
