Sony has released a rather comprehensive API for wifi control of their selection of cameras here: https://developer.sony.com/downloads/camera-file/sony-camera-remote-api-beta-sdk/
I have been searching for what methods to use so I can manually control focus. I have been able to set the focus mode into "manual focus", but I don't see any methods for setting the focus point. There are several methods for controlling zoom, which I would expect the same to exist for focus -- Yet, this feature is seemingly implemented in the sony playmemories android application, so it must be possible, I think... but as it's a black box it's hard to tell what focus mode it's calling.
Could someone share what the methods are for manually focusing the camera? I am on a sony a7r with the lovely 90mm macro.
The beta SDK from March 15, 2016 provides no information on how to do this. This is a key feature which is directly blocking my ability to do effective deep focus stacking.
