Cooke Panchro/i
Cooke Panchro/i Primes are
color matched and perform
like their S4/i and 5/i siblings.
In fact, all three lines are currently
concurrently in use on the Martin
Scorcese 3D film “Hugo Cabret”, shot
by Bob Richardson, ASC.
There are 6 lenses in the Panchro/i set:
18, 25, 32, 50, 75, 100mm, all T2.8-T22.
The front diameter is 87mm for all lenses.
Angular rotation from infinity to minimum
object distance (MOD) is 300°. Focus
and iris gears on each of the S4/i, 5/i and
Panchro/i series have the same pitch and
are consistently located in the same position
relative to the lens mount.
