Lens Data System
11.1.
The lens data system allows lens and camera
information to be shown on connected Lens Data
Displays. This information includes focus, iris and
zoom values for any position on the lens ring, the
resulting depth of field, fps, shutter and battery voltage.
The LDS enables iris compensated speed ramps
and delivers precise and reliable information about
lens and camera status for e.g. crane or Steadicam
setups in wired or wireless configuration. Together
with external distance measuring devices (UMT-1 or
Cine Tape Measure), it also allows focus tracking.
The LDS is compatible with all lenses equipped with ARRI
LDS contacts and lenses using compatible protocols.
The LDS status is indicated by the
LDS status LED
