Lens Homing
Lens homing is only required when using “External Encoders”
Lens homing is a calibration of the external encoders that is required any time that the encoders are rigged onto the lens, or the lens is swapped.
The process is similar to the calibration process a lens control system does when swapping lens and is essentially about teaching the encoders where the minimum and maximum ends of the lens barrel movement are.
A notification will display in the dashboard when Scenario expects lens homing is required.
Please note that the system is not always able to infer when homing is needed and as such it is recommended to monitor the FIZ values displayed in the dashboard for discrepancies with the real-world values, as this can indicate that lens homing is required
All lens homing is managed via the “Lens Encoder Management” window which can be found in the settings panel
The lens encoder management page will display the current information of the lens encoders.
In this example as a Prime lens is being used so only the focus barrel needs homing (Iris is not available with External Encoders)
To home the lens, while this window is open, simply rotate the focus barrel fully from minimum to maximum at least twice.
After this procedure, the barrel position will display in the UI
Ensure that when the lens is physically set to infinite focus, that the indicator in the UI is at the corresponding end of the scale.
If the indicator in the UI is showing the opposite to the physical lens position, then this must be inverted using the “Invert” button
