About Cooke Panchro/i Technology


Set of 6 Prime Lenses

Cooke’s /i Technology enables film and digital cameras to automatically record key lens and camera data for every frame shot and provide it to post-production teams digitally. It streamlines production and post, saves time and cost, and eliminates guesswork while enabling greater creative freedom.

Using /i Technology Means...

  1. You can have a continuous remote readout of the precise focus setting, T stop and depth-of-field from electronics inside the /i equipped lens so you will be able to see the actor in front of you and the focus setting on the lens beside you without turning your head or even having to move your eyes too much. ACs love it.
  2. You can digitally record vital lens and camera settings accurately, frame-by-frame, all synced to Timecode, instead of having to manually write down lens settings for every shot, eliminating human error. One task your script supervisor needn’t worry about.
  3. Normal operations on set are not affected. Metadata recording takes place without having to monitor or manipulate anything. Data records to digital or film recording medium or to an SD card. No specialists required on set and the DP needn’t worry about fussing with complicated accessories.
  4. You will streamline the production and post production processes to save time and cost while ensuring a better quality product because the digital data you can now provide takes the guess work out of the process. Artists create visual effects and 3D models that are more accurate, with much greater speed. ACs, DPs, Directors, Producers, VFX Artists – everybody wins.

Cooke's /i "Intelligent" Technology enables film and digital cameras to automatically record key lens and camera data for every film frame, which can then be provided digitally to post-production teams. The technology streamlines both production and post, saving significant time and costs and eliminating guesswork, while enabling greater creative freedom. /i Technology is standard on all new Cooke 35mm lenses.

"This technology represents the essence of forward compatible, forward thinking metadata support. Open source, anyone can use it, high degree of accuracy. Ten stars out of a possible five for providing for the digital future of cinematography. Bravo!" David Stump, ASC, DP/VFX Supervisor

"The use of this data provides more accurate results in faster time and removes yet another element of uncertainty from the set-to-post information transfer process. Its use will allow more complex shots to be completed and will also allow new types of shots." Michael Lancaster, product director, The Pixel Farm

Continuous Remote Readout

With the Cinematography Electronics /i Lens Display Unit you can have continuous remote readout of the precise focus setting, T stop and depth-of-field from electronics inside the /i equipped lens. Focus Pullers will be able to “see” where the actor is relative to lens focus and depth of field without turning their heads by using Cinematography Electronics' /i Lens Display Unit in conjunction with their Cinetape.

Record Vital Lens & Camera Settings

Manually writing down lens settings for every shot is now passé. Focal length, focus distance, f-stop, frame rate – vital camera and lens settings are digitally recorded for every frame, at any frame rate up to 60 fps, film or digital, and stored as metadata.

Digital cameras that are /i equipped (RED and SI 2K) talk to /i lenses directly via contacts in their lens mounts. The /i Technology provides the framework; the extent of camera data made available is the choice of the camera manufacturer via their software and software upgrades.

You can record the same accurate, frame-by-frame lens data using cameras not equipped with /i Technology by using /i equipped lenses and the Cooke /i dataLink. Lens data records directly to an SD card in the /i dataLink box via a cable to the lens. Normal workflow and operations on set need not be affected. It is as simple as that. The /i dataLink information will automatically be stored for the day’s shooting without the DP or AC taking notice of it. At the end of production, take the SD card(s) to sync in post via Timecode.

"On set, we just plugged in the lens and the camera, and the box records. It’s completely transparent." Devon Dickson, DP

Post Production

Metadata is passed through to post-production to improve VFX creation and DI calibration. Post production artists can sync the lens data to the 3D camera data to produce a more natural looking 3D model of the shot significantly faster than using traditional manual processes and guesswork.

Improve Accuracy & Speed

"By having access to lens metadata, the PF Track software came up with a solution an order of magnitude faster than by its algorithms alone, and the result was much more accurate because it was based on real camera data. This workflow brings production and post infinitely closer and benefits both artistic quality and production time." Michael Lancaster, product director, The Pixel Farm

Technical Specifications

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 mount that sync with i/ compatible cameras and accessories.

Colour Balance - All Panchro prime lenses are colour balanced to a specification within parameters approved by Kodak.

Aperture - All Panchro primes have a true T2.8 aperture and cover Super 35mm format.

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 - Arriflex PL Mount.

Focus Scaling - Large, clear numerals on both sides of the focus barrel benefit the focus puller when shooting under difficult lighting conditions.

Compatability - All Cooke Panchro primes have a common fixed front diameter of 87mm, except for the 18mm (110mm), with a focus drive gear of 121T x 0.8 mod and an iris drive gear of 119T x 0.8.

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 - An eight-leaf linear module iris assembly is fitted into Panchro primes with an aperture range of T2.8 to T22.

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 prime lenses are designed to meet a market requirement for fully reliable performance with a minimum of downtime.
