I want to buy a speedlite and a ST-E2 so that I can get it off the camera for portraits and I also want to be able to use a softbox or umbrella for softening/controlling the light. Eventually I want to buy two speedlights I know one of these lights will be a 580EX ll - I am not sure if I should also buy a 430EX or second 580EX ll.
My delima is should I start with the 430EX and ST-E2 for about $450 and learn with that combo? Can I use the 430EX as a key light along with a difuser? OR should I go ahead and add $200 more to the bill and start with the 580EX ll and a ST-E2? Will there be that big of a difference between these to lights if I could only have one speedlite to work/learn with?
