my wife has decided that we need to get a good dSLR to take pictures of our kid. I don't really know much about photography, but I'm kinda interested in learning. since my father has a Nikon D80 I was thinking I'd get a D90 or D7000 so I could borrow his lenses from time to time. people seem to have really good things to say about both of these models. which one should I get? do they have enough automatic modes that my wife, who is sometimes reluctant to learn anything new regarding technology, can kinda point and shoot with it?
