    Got an old Sunpack flashgun laying around, just wondering if anyone knows if it's save to use with a modern camera like the Lumix G3. Just wondering if the voltages may be different and risk damaging the flash or the camera?

    I think the voltage is different and its best not to use them. But I could be wrong.

    I've known modern cameras to be ruined by old flash guns. Please research toSmile be safe.

    Easy way to avoid problems is to get a 10 radio trigger.

    Thanks mad-dogs, wasn't on that list but some extra googling and it's apparently 5.5V, from what I can find the G3 requires a low voltage, one website says

    A high voltage flash is quite safe, if you have a flash socket on your camera for off camera flash. Its only when you use the hotshoe that you are limited to 5 volts. I have a 5D camera that is quite OK to use the external flash socket.

    I wouldn't risk that. The internal circuitry to the hotshoe is the same as to the flash socket I suspect. Better safe than sorry if you want to avoid frying the electronics of an expensive camera just to save the price of a 9.99 radio trigger.

    I would heed LeftForum's warning. Attaching by a lead to a 3mm socket on the camera is the same as putting it in the hot shoe. Use a radio trigger.
