Dear Professor, for architectural photography, I would say you might want wider angle most of time. If so, a DX camera would tie your hands sometime. Another DX camera wouldn't help in this matter either. If now I had a D90, I would wait for a better FX body instead. Even though I love my D7000 very much, I actually thought about selling it and get a D90 and then wait for a better FX body. But suddenly the price of D7000 dropped by 200 dollars. Well now I have to hold it, of course,with loving it.
