Hello all, I have these wireless triggers i bought on Ebay, you know the kind - 4 channels, cheap build, work pretty well. Anyhow, i'm trying to find out whether or not the receiver can be connected to the flash some other way, and not through the hot-shoe. This is because when attached to the receiver, the flash isn't very stable screwed onto my flash stands. It wobbles and generally doesn't inspire confidence. Also, i think it puts the flash further from the umbrella's axis than it shoud be. So, is there a way?There's some sort of socket on the receiver, but i'm not sure what it's for. It looks exactly like one of the sockets on my 580II. Anybody know what i'm talking about? Thanks, Emil.
