I'm looking at getting a trigger for my 6D, and currently have a 430II EX flash although I'm looking at adding one maybe two more flashes sometime in the future.
I have been looking at both the canon triggers and delving into the flash photography world, and I right in saying that if I get the ST-E3-RT that I would also need to buy a receiver for my external flash, or will it still fire with out? (I assume it's a radio transmitter only and not IR?) It's only going to be for home personal use at the moment, so would I also be better suited just getting the ST-E2? I'm not really planning on doing any outdoor shots until I get confident and comfortable with flash photography.
I've only really looked at cannon for now, are there any other recommendations people can give?
Thanks!
