Hi,
I was looking for the trigger voltage for an old flash unit and couldn't find the info in any of the stickies/posts etc but came across this page through google:
http://www.botzilla.com/photo/strobeVolts.html.
I have no idea how accurate this information is but maybe someone who knows more about it may be able to have a look?
Please do not blame me if you fry your camera.
