HI I am new to off camera Lighting techniques. I own a 580 EXII. I am planning to try my hand on off camera lighting. Initially thought of getting the cable as a start up. Then saw the Youngnou YN-622C wireless trigger. So thought of jumping straight to wireless and skip the wired part (not sure how good an idea that is. thought of saving some money in the long run). I have plans to get a 430 ExII later. My Question is, if I use YN-622C, can I have the 580 be an off camera master and wirelessly trigger the 430 ExII or do I need to get a third YN-622C for the 430 exII?
