sanj said:Interesting thread. Buying a flash to control the 600 ex-rt seems to be the smart option. That way I can have 2 flashes for the price of 600 and the controller.
Question pls: What is the smallest flash I can buy to put on 5d4 that will control the 600? This way I can use the small flash independently for family/casual photos...
The 600 EX-RT functions in master and slave mode, so you need another one to control the off camera flash.
Downside is that one flash has to be on camera or have a pc cord.
