LDD-FP graphically shows depth of field, and allows for the setting, displaying and storage of focus marks.
Because of its small size it can be mounted in many ways, allowing the assistant to see precise lens and
camera information while keeping an eye on the action.
The LDD-FP shows camera information depending on the detected camera type. From ALEXA SUP 6.1 on,
specific ALEXA status information, like remaining SxS recording time or digital recording specific camera
status colors will be displayed.
