To calibrate different zoom and focus steps it´s necessary to read out the internal or external encoder of the lens.
You can use different protocolls / products to read the lens values inside of Stage Precision like:
- Phidget Encoder
- C-Motion Motors
- Arri Bodys
- FreeD supported encoder
- and for sure all supported camera tracking systems or PTZ heads.
To use one of these you need to add the respective IO connection and create a map input inside the camera object.
