Cooke 25mm Panchro/i Classic T2.2 Full Frame Prime Lens.
The original Cooke Speed Panchro, designed by Horace W. Lee in the 1920s, was a cine prime lens that chromatically enhanced an image when filming under restricted illumination. Cooke Speed Panchros combined a relative aperture as wide as f2.0 with an angular field of view and definition previously impossible with much smaller apertures. They quickly gained a worldwide reputation for quality cinema production and were widely used throughout the 20th century.
Available in focal lengths: 18, 21, 25, 27, 32, 40, 50, 65 MACRO, 75, 100, 135,152mm.
Optical Design
The optics are designed to give maximum performance at full aperture with superior control of flare, distortion and spherical aberration.
Electronics
Accessible via contacts in PL mount that sync with /i compatible cameras.
Colour Balance
All Panchro/i Classic prime lenses are colour balanced, colormatched and compatible with Cooke 5/i, S4/i, miniS4/i and Anamorphic/i.
Aperture
T2.2 to T22 except 18mm, 100mm and 152mm.
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 Panchro/i Classic primes have a common fixed front diameter of 110mm.
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
A nine-leaf linear module iris assembly is fitted into Panchro/i Classic primes.
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
Panchro/i Classic primes lenses are designed to meet a market requirement for fully reliable performance with a minimum of downtime.
