So right now I have a pair of yongnuo 603's and they work great for manual mode, etc. I'd like to upgrade to something with ETTL and the ability to add in a 3rd speedlite and control each one's power individually, etc. The ability to work also with something like an AlienBee would be great in case I ever get a strobe.
I was looking at the Yongnuo YN-622's, but a little confused. It seems like these would be what I want to get the job done?
But then I could also get them plus this controller here:
I'm guessing the controller allows you to just control them from one location? I'm trying to figure that part out. Also, if ever I needed to put a speedlight in the hotshoe, and then use 1 off camera flash, wouldn't I need a controller with a hotshoe hookup?
