Cooke S4/i Prime Lenses With Intelligence
The same Academy Award-winning Cooke S4 lens optics, but with electronic intelligence.
Adjustment of the Soft Focus Effect
Our S4/i lenses are designed for all professional motion picture film cameras. The S4/i system provides cinematographers and camera operators with vital information on lens setting, focusing distance, aperture and depth-of-field, hyperfocal distance, serial number, owner data, lens type and focal length in both metric and footage measurements. For zoom lenses, the zoom position is displayed.
The S4/i system -- winner of NAB2007 Premiere Product Award -- is designed for use with LDS equipped cameras, and for use with any professional film camera -- 16mm or 35mm -- using a /i Lens Display unit, provided by Cinematography Electronics. In addition, lens display software for your PC is available for free download here: PC Viewer. (Necessary cables or Cooke Bluetooth™ transmitter required.) Pocket PC and Palm versions will be available for download soon.
Absolute encoders positioned inside the lens monitor focus, zoom and iris settings to ensure that outputs are available immediately from "power on."
Electronic microprocessor and software are embedded in the lens that read focus, zoom and iris settings and calculate important picture format data. This data and current settings are then transferred via a serial link to either an Arri camera equipped with LDS via the LDS contacts within the mount, or via the lens' external connector to the Cinematography Electronics S4/i Data Display unit.
Pre-adjustment or pre-setting is never necessary.
The Cinematography Electronics /i Lens Display unit interfaces the Cooke S4/i lens system with their popular CineTape Measure System, and adds lens data previously not available: actual measured subject distance. The focus puller will now know where the subject falls within the depth-of-field for the particular lens being used. This data is continuously updated and displayed for real time information.
