Cooke Mini S4/i Prime Lenses T2.8

BP #: COOKE-MINI-S4

Please call for Pricing and Availability

Quick Overview

The miniS4/i Primes (T2.8 to T22 aperture) incorporate everything that today's filmmakers ask for: smaller, lighter-weight lenses that offer the same resolution, optical quality and reliability as the S4/i lenses at T2.8 speed. With the speed of the new digital cameras, T2.8 is the new, economical T2.0. The Mini S4/i’s are interchangeable with the S4/i and 5/i lenses for shooting film and digital images up to and beyond a 4K resolution. Current Mini S4/i focal lengths are 18, 25, 32, 40, 50, 65, 75, 100 and 135mm.

What we heard from the industry

While many DPs prefer to specify Cooke lenses to take advantage of the Cooke look as well as the on-set usability and reliable operation, cost has sometimes been a barrier. In addition, many purchasers of digital cameras like Red also want a full set of lenses at a realistic price.

We also wanted to open up the opportunity to use Cooke lenses in risky situations such as on-board stunt work; lower costs lenses reduce rental and insurance costs.

S4 Quality Deserves the S4 Name

Our goal has been to deliver a smaller, lighter lens which offers the same resolution, optical quality and reliability as the S4/i, but at a lower price. We decided that the lenses should be equally suitable for shooting film and digital images up to and beyond a 4K resolution pipeline.

In addition the lenses include /i Technology, providing lens data per frame for downstream post production. Like the S4/i lenses, the miniS4/i's are designed for motion photography and they don't breathe.

The lenses are one stop slower than the S4/i, as a result they can be smaller and lighter.

All Cooke lenses are colour matched. This means miniS4/i and S4/i lenses can be mixed on a shoot with full confidence that the images will match.

Optical Design The optics are designed to give maximum performance at full aperture with superior control of flare, distortion and spherical aberration.
Accessible via contacts in PL mount that sync with /i compatible cameras.
Colour Balance
All miniS4/i prime lenses are colour balanced to a specification within parameters approved by Kodak.
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 Arriflex PL Mount
Focus Scaling
 Large, clear numerals on both sides of the focus barrel benefit the focus puller when shooting under difficult lighting conditions. Plus the the Entrance Pupil position is engraved on the lens.
Compatibility 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 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.
Reliability and Service miniS4/i prime lenses are designed to meet a market requirement for fully reliable performance with a minimum of downtime.
