... it can be used as an optically-triggered slave flash, I gather.
But I'm new to this game, how strong does the on-board flash have to be to trigger the external? The whole point is that I'd be trying to move the source of light, it strikes me as a waste to have both of them going at once...?
...also, I've got the GF1, and I keep hearing things about pre-flash messing up optical slaves, can that be overcome?
