I have a flash gun that i used with my old eos 300. It doesn't work with the 30D and I'm struggling to find data on whether its the 30D thats not working or just not compatable. (The flash still works with the eos 300)

Anu suggestions. Thanks

Ned

It needs to be an ETTL flash gun to work with the digital cameras. In canon terms that means it has an EX in its name.

On ETTL cameras the gun flashes a little bit of light just before the mirror lifts to measure the power required, and then sets the flash duration.

Fitting a non ETTL gun with either result in the gun being set to maximum, or firing all its energy at the mirror lift event.
