I can tell for sure that the Metz 45 CT-1 did NOT fried my K5
My serial number is 434xxx so annouced by Metz as delivering pretty high voltage (over 400V) and my camera still works good. Onboard flash unit as well.
All that happend this morning, a neighbour found the Metz in the street (so is Berlin), and bring it back to me. I knew the potential issue with high voltage on hot shoe mount but I thought it was ok thru cable... since then I rode quite other story :S but luckily my camera is perfectly fine. I shooted like 20 times with eneloops fully loaded.
Now I have a pretty powerfull torch, and no reason anymore to fear any problem.
Being idiot has advantage sometimes
This said :
- I trust Metz about there annoucement, my metz should deliver high voltage according to serial number : I haven't checked myself it was so, may be a mistake on their side saved my ass more than high voltage protection on K5 PC plug.
- I would not say that it is safe to plug a K7 or a K5 II etc.. as may be some specifications could be different, who knows.
