Hi to all you Nikonites. I have a question. I am doing off camera flash. I have a sb-5000 and 3 - sb700s. I have a godox xpron ttl trigger and 4- xir n receivers. When i put the sb-5000 in remote and put the sb-700s in remote they do not fire. But when they are just on is this the only way they will work? And when the sb700s are in remote. Is this only for the c.l.s. system? Could someone please advise me on this. Although when nthey are in master on the sb700s they will work. But only two channels. I am also only doing just ttl. Thanks to anyone who can let me know.
