COOKE MINI S4/i
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.
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.
All miniS4/i prime lenses are colour balanced to a specification within parameters approved by Kodak.
All miniS4/i primes have a true T2.8 aperture and cover Super 35mm format.
Every index mark is labelled. More detailed markings allow for more detailed focus control.
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.
Arriflex PL Mount
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.
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.
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.
An eight-leaf linear module iris assembly is fitted into miniS4/i primes with an aperture range of T2.8 to T22.
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.
