[400dabuser]

i recently went to a demo, in which they demostrated how to use the wireless trigger for the flash guns that was set up on the stage. the problem is that i forgot what the model number is called. its either st2 or something like that from canon

There's a lot of information on here about the ST-E2. There's pros and cons to using it.
