So I just purchased a used D700 and when I try to use the flash compensation button and rotate the command dials, nothing happens. I do this with the flash raised, and if I take a picture, the flash works great. I can go into menus and set the flash to manual to adjust levels, but I can't set the type of flash using the rear dial, and I can't adjust compensation with the front dial. Is there some setting somewhere that could disable the compensation button on the side of the body? I'm almost at the conclusion that this button is broken. Nothing different happens with my SB600 mounted either.
I also just upgraded my firmware and it did not fix anything.
Any ideas before I need to work out something with the seller on getting this looked at?
