Well, I'm after one of these bodies. I currently shoot a D300 and a D700 or D3 would go nicely with it, however, I already have an MB-D10 for my D300. Now, what will the D3 give me that the D700 won't? I mainly shoot, portraits and weddings and events. I rarely shoot any sports and rarely use AA's to get more than 5fps. So, at the exclusion of faster AF lock, and more fps, what will the D3 offer me that the D700 won't? Is it really the same image quality?
