The DJI Camera compatability chart claims that the USB-C control cable disables IBIS but not OIS when in PC Remote mode. It does not claim this with the Sony Multi Cable option.
When I use the either cable...it doesn't seem to prevent me from selecting different Steadyshot settings including "Active Mode" where it does the crop for me so I assume that it is still working?
But when I select the Button I assigned steadyshot settings to I get a "Connected to PC Remote. Cannot be executed" Sony customer service told me that it would not disable the IBIS in PC Remote...very confusing.
