I'm just beginning to think about diving in to flash/off camera flash photography techniques. If i understand correctly my d300 can act as a commander to sb600/800/900's right? To use those off camera, i wouldn't need a pocket wizard would I? If that's the case, my setup is a fairly common one, most people interested in off camera flash will have camera's with built in commander modes so why do pocket wizards exist? What am i missing? Do they increase the range? Does the wireless synching not work as i'm thinking?
