The Sony adapter output socket is correct size (I realise I need to check the polarities are the same).
But I still have a number of questions: I would assume that both of these devices will require a regulated output - is there anyway of telling?
Assuming that voltage outputs are the same, both are regulated, and polarities are correct, then there will be no harm in trying the Sony with the Fuji.
I would have thought that this question must be a common one - but I can't find answers via Google. Can anyone answer the specifics or point me to a good source?
