Creating beautiful images for the motion picture industry

A legacy of superior and innovative lens design and manufacture under the Cooke name that continued throughout the 20th century beginning with still portrait, telephoto and process lenses, through the development of acclaimed Cooke cine and television lenses, and continues today by Cooke Optics Limited, with award winning 35mm cine prime and zoom lenses.


Tradition of Innovation

For over 100 years, Cooke has been at the centre of the filmmaking business. We've been listening to the community of which we are a part. We lead by introducing new

products such as /i Technology, and we remember our success is built on a simple idea - do what the filmmaker needs.

 
 

panchro classic
panchro classic i 75mm
 
 

The growing demand for vintage Cooke Speed Panchro lenses from the 1920s to 1960s prompted us to introduce a modern redesign of the vintage classic.  We are pleased to introduce Cooke Panchro/i Classic, T2.2 to T3.2 Prime lenses. 

Our new Pancho, that is true to the original look of the now legendary Speed Panchro, recreates the same look and feel of the original with the advantage of modern glass mounted for today’s cameras. And, the new lenses come equipped with /i Technology for frame by frame digital information capture, as do all modern Cooke cine lenses for film and digital capture.

 
 

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.

 
 
 

Panchro/i Classic Main Features

Optical Design The optics are designed to give maximum performance at full aperture with superior control of flare, distortion and spherical aberration.
/i 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.

New Variable Vignetting Stop

Cooke's new Variable Vignetting Stop allows the high speed CXX lens to maintain T2.0 and high resolution throughout the zoom range. This innovative mechanism adjusts automatically. The benefit to you: no ramping and no flare.

 
 

Light and Bright

T2, of course. Light and comparable in size to a Cooke S4/i prime telephoto lens. And like our S4/i telephoto lenses, the CXX zoom offers an extraordinary close focus: Under 7 inches from the front element. And like the Cooke S4/i Primes - no breathing.

See in the dark -- with T1.4 speed and a focus ring that illuminates when you need it.

External lamps are no longer necessary for the focus puller to see in the dark because this new design incorporates a simple on/off and dimmer to adjust the level of illumination desired on the aperture ring. You now have the visability you need without affecting the light coming into the camera.

cooke anamorphic
 
 
65mm anamorphic macro

All of the anamorphic lens characteristics demanded by filmmakers today with the Cooke Look® and oval bokeh. That’s the Cooke Anamorphic /i Look. Images beautifully rendered for film and especially suited for use with digital cameras.

The Anamorphic /i lens correct aberrations exceptionally well over the entire image area – astigmatism, lateral and longitudinal colour – that will render shape, form and soul to your images.

While the "look" is crucial, precision engineering and seamless integration with other equipment is equally important. The Anamorphic /i, prime lenses in ten focal lengths are colour matched to our S4/i, 5/i and miniS4/i lenses.

 
 

Ideal for close-ups and product shots, the Cooke 65 mm Macro Anamorphic /i 2X Prime lens has magnification ratio 4.1:1 with close focus of 5.5" from front of lens.

Now, you have even more latitude. We went one step further with our new Anamorphic/i SF lenses that are specially manufactured with a coating that allows for even more creative options. The “SF” stands for Special Flair because they allow you to kick the flares, bokeh and other aberrations into new visual territory.

Complementary to the Anamorphic/i lens series, they are offered in 25mm, 32mm, 40mm, 50mm, 75mm, 100mm, 135mm, 180mm, and 300mm focal lengths.

The Anamorphic /i lenses offer superb optical and mechanical performance. Distortion, veiling glare, flares, and all aberrations are controlled at all apertures over the whole field of view. Like our S4/i, 5/i and miniS4/i prime lenses, the cam focus mechanism allows for smooth focus adjustments. Modular construction increases ease of maintenance and serviceability.

The Anamorphic /i lenses are designed and made by us to our traditional high standards in Leicester, England.
