Panchro Classic Main Features
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 Panchro/i Classic prime lenses are colour balanced, colormatched
and compatible with Cooke 5/i, S4/i, miniS4/i and
T2.2 to T22 except 18mm, 100mm and 152mm.
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.
Cooke Hardened PL Mount with /i Technology contact.
Large, clear numerals on both sides of the focus barrel benefit the focus puller when shooting under difficult lighting conditions.
All Cooke Panchro/i Classic primes have a common fixed front diameter of 110mm.
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.
A nine-leaf linear module iris assembly is fitted into Panchro/i Classic primes.
The lenses are designed for all shooting applications, including handheld and Steadicam, providing comfortable balance ratio with the latest compact cameras.
