Hi,
I have the actions to control lens settings on cameras but they require the current beta version of PlayMaker, as Cinemachine support will be the first set that benefits from major improvements in the way actions can be developed and their features.
If you are part of the beta, let me know, I'll give you access to the current cinemachine package, else let me know if you prefer to wait a few day ( should be out any time now, we are actively debugging the last RC release), or you could apply for the beta and work on it right now ( provided beta releases are not supposed to be used in production)
Bye,
Jean
