Optical
Design - The
optics are designed to give maximum performance at full aperture with
superior control of flare, distortion and spherical aberration.
Colour Balance - All
Cooke Series 4 prime lenses are colour balanced to a specification
within parameters approved by Kodak.
T2 Aperture - All
Cooke Series 4 primes have a true T2 aperture and cover Super 35mm
format.
Index Marks - Every
index mark is labelled. More detailed markings allows for more
detailed focus control.
Focus Movement - A
newly designed non-linear focus movement (Patent pending) 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 - The
Cooke Series 4 primes can be supplied with either Arriflex PL or
Mitchell BNCR mounts.
Focus Scaling - Large,
clear numerals on both sides of the focus barrel will benefit the
focus puller when shooting under difficult lighting conditions.
Compatibility - All
Cooke Series 4 primes have a common fixed front diameter of 110mm,
with a focus drive gear of 140T x 0.8 mod and an iris drive gear of
114T 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 - A new
eight-leaf linear module iris assembly is fitted into the Cooke
Series 4 primes with an aperture range of T2 to T22.
Weight/Size Ratio - The
lenses are designed for all shooting applications, including
hand-held and Steadicam, providing comfortable balance ratio with the
latest compact cameras.
Reliability and Service - The
Cooke Series 4 prime lenses are designed to meet a market requirement
for fully reliable performance with a minimum of downtime.
