Ok, got a good idea. Keep the D7K, and save up for a D700. Use the D7K and my lightweight DX lenses on the road, and the D700 for macro and portrait work. I'm not in a hurry, in fact waiting might be good to let used D700 prices go down even more. The D700 is a good, tough camera that I should get years of service out of. I don't need the latest and greatest necessarily. Just a good dependable FX.
As far as the lenses you mentioned, that will have to wait. But at least I will have the camera that can utilize them. Nothing written in stone of course. I may find a good deal and jump on it. You never know.
