In my thought process regarding benefits of D3 vs D700, I am wandering if someone can help me answer a question. If I have a D300 and want to use its built-in flash in commander mode, wound a large lens with a hood (e.g. 17-35mm f/2.8 or 24-70mm) mess up the exposure. I am asking this because with the hood on, the biuilt in flash is useless with that lens for regular flash photography. I suspect it will not get the exposure right, but I am not sure. Any one know the answer?
