I quickly tried the direct method for ISO, f-number and shutterspeed and
can confirm that I can now change their values on the Sony A7S III.
So no stepping, just setting the values directly. I added the
direct setting function calls using the device specific menus again.
PTP_DPC_SONY_ShutterSpeed2 seems like not detected with this device,
otherwise it would have probably automatically already used the direct
method.
Photo capture is working now, but the Autofocus trigger doesn't work yet.
At least it is starting to get somewhat usable now.
Kind regards, Jeroen
