Right now I have a 5D3 and several L glass lenses. I also have two 600 ex-rt lights with stands and umbrellas. I either need one more to control the others or the remote they made for it. The reviews on the remote were not te greatest because of the lack of low light focusing ability. I am thinking it may still work for me and it's cheaper than buying a 3rd flash. I could also decide to just get a few actual strobes, but they are so expensive and I hear you can do just as good with speedlights. Thoughts? Suggestions? I shoot events and weddings, but want to shoot models and boudoir as well.
