Hello guys. First off, i want to say that i'm a newbie when it comes to flash/strobe photography. I've had two Canon 600EX-RT and a ST-E3-ST for about two years now. I recently picked up my first strobe and it came as a package; PCB Einstein E640, Cyber Commander, Cybersync Transreceiver, and Vagabond Mini. How do get my canon stuff to work with the E640 and Cyber Commander?
Gear Summary:
Two Canon 600EX-RT
Canon ST-E3-RT
PCB Einstein E640
Cyber Commander
Cybersync Transreceiver
Do i need to purchase other transmitters or am I able to keep what i have and add a few receivers to my setup?
Any help would really be helpful. Thank you.
