I have an issue where Manual lenses won't focus (I think I have seen a similar problem with a post about a Ronin 4D).
The issue occurs when faces are detected in the scene in AMF (either wide or smart). As soon as the ronin detects a face is backfocuses somewhere behind the subject. LiDAR and lens are calibrated properly (autofocus is perfect when the camera can't detect a face in the scene).
