Thanks for your reply, but Which flashes are ‘approved’ is not the question, I could find that out on the website, too. Alone from a marketing standpoint, it is quite obvious they a 70-year-old flash would not be on the approved list, when one of their own manufacture that is seven years old is also not anymore compatible... What I am looking for is advice on not how to make it compatible (actually impossible), but how to make it WORK without damaging anything; the rest I can work out myself. The old single centre-contact cameras could handle any voltage thrown at them, as they were only a connect-to-earth switching affair. With electronics things look very different. There must be shielded/protected connections or hot shoe adapters out there - especially as the newer cameras no longer have the synch cable socket. The lack of that socket is the cut-off point for me, where I have to call in those that have more knowledge than me on the subject! All the best, Peter
