Useful link thanks. I have an old Metz that is compatible with my EOS 3 and thought it should be OK on my DSLR's but contacted Metz first who gave a very emphatic no saying it would damage the modern cameras. Good job I asked first!

For measuring trigger voltage of old flashes you should use a Digital Multimeter other analogue meters do not show the Peak Voltage,thanks.

Thanks for the link, Mo.

I was given a Canon Speedlite 420EZ a few years ago, I could get one flash from it but nothing after so the communication between the camera and flash must be different, so I taped over all the connections on the flash except the centre one, connected it to the camera and nothing, I then let one of the pins come through the tape and connected it again to the camera and it worked so I disconnected the other wires inside the flash and it works every time now but only in manual mode but this is how I was brought up so no worries
