Discovering that my ancient studio monoblock - a Courtenay Sola 8 Mk 111 - still works, I was intending to use it with my D200 and D700 until this morning when I discovered this on the Internet, referring to another model in the Courtenay stable (I assume they are all the same idea under the skin) and I quote:
"They have a NEGATIVE polarity synch. lead and should not be connected to any digital camera - especially consumer digicams with purely electronic shutters - without using an isolating flash synch. box."
Has anyone heard of this before, and would that indicate that a remote Wizard(?) thing is the only safe way to use old flash?
I'm sure that I once tried the thing out with the D200, but it might have been my Metz 60 CT instead. However, the Metz definitely doesn't work right now - won't charge - so I suppose that a new battery is in order. Whichever flash that I did use, I noted no problems with the camera afterwards.
Any knowledge would be useful!
