5th generation intelligent hand unit

The new ARRI Hi-5 is the most sophisticated hand unit on the market, providing reliable wireless camera and multi-axis lens control. Weatherproof and solidly built, it features an exceptional radio link range and unique, swappable radio modules for different territories and shooting challenges.   

A lens table is transmitted to the Hi-5 from the camera device where the lens data is generated. ALEXA Mini and Mini LF cameras, the Universal Motor Controller UMC-4, the cforce mini RF lens motor, and the Radio Interface Adapter RIA-1 all support wireless lens file transfer. Classic ALEXA cameras including the Plus module load lens files from an SD card. Buy ARRI Hi-5 unit from UBMS Dubai.

Lens data is generated on the camera side and displayed on the Hi-5. The data is generated in one of two ways:

  • From LDS lenses, via the internal lens encoders
  • From the Lens Data Archive (LDA), via the motor encoders

The Lens Data Archive (LDA) is an archive that contains lens tables. Those lens tables set the raw motor encoder values in correlation to the actual lens scales. Once you choose the right lens table from the Lens Data Archive and calibrate your lens motors, you get the same type of lens data as an LDS lens would deliver. You can create your own lens tables for any given lens with the Hi-5 and save them internally, externally to a USB-C flash drive, or in an iOS device with the ECS Sync App. Lens tables can then be transferred wirelessly from Hi-5 to the ALEXA Mini/Mini LF, the Radio Interface Adapter RIA-1, the Universal Motor Controller UMC-4, or the cforce mini RF lens motor.
