I have two Yongnuo YN-568EX-II speedlightsspeedlites. I can use them as radio/receivers between the two, but I want to use a controller on camera to be able to use the speedlights off camera without losing E-TTL and HSS.
Which controller(s) allow for off camera placement while maintaining E-TTL and HSS?
I'm currently thinking of the Yongnuo YN-622N622C-TX—but is this compatible? Is there a compatibility list?
