Arricam ST
The most innovative feature of the Arricam is the Lens Data System (LDS) which reads and controls all data of the lens.
................
It consists of Zeiss Ultra Prime lenses or Cooke S4 lenses that contain contact sensors.
These sensors electronically transmit the settings for focus, iris and zoom to the camera.
Here, the other external systems, such as, the Arri lens control system, with which the lenses can be remotely controlled, receive the lens data.
The LDS system reads the iris and focus distance and uses the information to compute the depth of field.
When using the iris of the lens to ramp speed, the data is entered into the speed box and the camera finds the proper iris settings automatically.
................
For a high resolution video image, the Arricam employs a high speed ½" video camera and a video optic module with a 1.2 aperture.
Editing quality is achieved even under low light conditions.
All data on the on-screen menu can be stored and retrieved later.
Manual white balance has been added to the standard indoor, outdoor, and automatic white balance settings.
The film image and video image exposure time can be synchronized in order to match the film's motion blur.
Vertical video resolution during camera run has been improved.
................
A Genlock socket, on the video assist, is used to synchronize external video signals to the film camera.
All functions of the video assist may be controlled remotely.
The camera display has been expanded to include all lens data information.
