Speedlights w/ Cybersync's
Not sure if this is the right forum, but here goes.
I currently own a number of Alienbees with Cybersync radio transmitter/receivers. I want to supplement these with a couple of new Canon 580EX's. I know it is possible to trigger one 580 in manual mode with the Cybersync's, but if I add two more 580's can they be triggered by the first Cybersync'ed 580 ? Basically, I don't want to buy the ST-2 transmitter if I don't have to, or more Cybersync's, and I also want to mix the 580's with my Alienbees in one setup on occassion.
I know I will lose the E-TTL functionality if I use the Cybersync's to trigger the 580's, but that's okay.
Thanks for the help.
