So i've never used a speedlite, and i'm unfamiliar with how they work exactly, especially off camera.. but i'm torn between the 430 ex and 580 ex ii
i want to eventually get 2, so that i can do outdoor portraits with a main light and a fill light.
Should i just get the 430 now, and then the 580 later? or start off with a 580?
As far as using either model off camera, will i need to use a pocketwizard for wireless, or a wire to make it work?
