Hey guys, I have been trying to set up off camera flash for a while and I kinda have some mismatched equipment. I think I have everything I need but I cannot make this combonation work. What I am working with is a Canon 50d, 580exII, one pocketwizard plus II transceiver, and a pocketwizard minitt1 trasmitter. I thought that you could use the new minis with older plus II's but I am having extreme difficulty. I thought you simply connected the mini to the camer and the plus II to the flash and away you went. Anything helps and I really appreciate it.
