OVERVIEW
- Covers S35mm Format Sensor
- T2.8 Maximum Aperture
- Color-Matches All Cooke Lenses
- /i Technology
The 50mm T2.8 miniS4/i Cine Lens from Cooke features focus scales marked in feet and is one of a set of lightweight companions to Cooke's already established S4/i lenses. The miniS4i lenses feature an aperture range of T2.8 to T22, while maintaining the same world renowned Cooke image characteristics.
This 50mm prime lens features a PL mount, which makes it compatible with most commonly used professional film and digital cinema cameras. Color-matched to intercut with other Cooke lenses, this lens combines classic, hand-fitted construction with a linear iris, cam-style focus, and /i Technology. If you are interested in a more vintage look, Cooke has optional un-coated lenses that you can use to replace the coated optics in your miniS4/1.
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.
Aperture
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.
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 anodized 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
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.
