Focus scale display not appearing on Arri WCU-4 wireless handset with Alexa XT
What the thread found
- Manual lens profiles must be created and stored on the camera's SD card to enable the depth of field scale display, even when lens data is already showing on the handset
- Creating a lens profile requires manually entering approximately a dozen data points for each lens
- A separate lens profile must be created for every lens type, and the profile must be manually switched on the camera when changing lenses
- The WCU-4 system can work with any lens type if manual values are entered, not just LDS-equipped lenses
- The system can incorporate focus information from a cinetape distance measuring device via the Arri UDM-1 interface, which allows autofocus capability
- Lens serial number variations mean profiles should be created individually for each job rather than shared across different equipment kits
Depends on
- The discussion occurred in 2016, and future firmware updates may have changed this requirement
- The exact procedure for manual data entry on the SD card is not detailed in the thread
- The precise setup and cabling configuration for integrating the distance measuring device is not fully explained
- This was user experience on Alexa XT with Cooke Anamorphic lenses, compatibility with other camera and lens combinations is not confirmed
