Cooke Optics S4/i 35mm/Super 35mm Prime Lens PL Mount 21mm T2

This Cooke s4/i 35mm/super 35mm prime lens PL mount 21mm is one of the S4 family of lenses.

The S4 design replaces the usual helical thread method of focus adjustment in favor of Cooke's Academy Award®-winning cam mechanism. The smooth cam movement frees the lens from a simple thread rotation giving the operator an appropriate rate of focus at all distances. The cam design also permits better spaced and more detailed and visible index marks. The S4s are renowned for superb control of flare, distortion, veiling glare, and spherical aberrations at full aperture.

All focal lengths are colour balanced, achieving excellent contrast and resolution over the full Super 35 format.

Cooke S4/i lenses come fully equipped with /i "Intelligence"; digital technology. This can save significant time and cost in production and post by streamlining  the processes and eliminating guesswork. This gives greater creative freedom and a higher quality final product.

Cooke Series 4 lenses are optimized at maximum aperture, measured at a true T2.0.  The Cooke S4 300mm lens is measured at a true T2.8.

The focus and iris drive gears have the same diameter and position across all the available focal lengths. This reduces adjustment time when changing lenses: 140 teeth 0.8 Metric Module x 6.0mm Wide (98mm from image plane).

For attaching film lens accessories, the front diameter of the 12mm focal lengths is 156mm.  The front diameter of the other focal lengths is located in the specification table for each of the other lenses.

Each of the Series 4 Primes are supplied with PL mount and are available with either footage or metric focus scales.

Custom carry cases are available.
