A few more questions if you would... What do the numbers closest to the camera body on the CFE lens do? It has a lightning bolt on it around the 90 mark. From reading, I understand that that setting is for flash. But, what do I do with it if I am using strobes? Where do I set it, or does the camera do it? I have a winder for it, but cannot get it to actually wind. It works, but does it work in manual mode? I heard I can only be in manual mode to fire strobes with a pocket wizard. Is that true? Sorry for such basic questions, but, I have read and read, and can't figure these out. I sat down tonight with a polaroid back and took the same photos with different settings, but, I still am not sure what I am doing.
