Hi, I upgraded from my D80 in the early days of the D7000. Learnt a lot about it and it's great features, but also its foibles and idiosynchracies! Auto-ISO and flash for example, U1/U2 saving and loading - and the feedback I had from Nikon on the design of U1/U2, LiveView on Sigma lenses not working and quite a bit more. Much of this is now posted on my web site;

It's a great DSLR, capable of very sharp photos. Need pro level lens though to get the best from it's Auto-focus.
