Congratulation on your selection of a good wife . That brought you to the D7000. Its a great camera that you will enjoy over the D5000 and 5100.
Its a truly amazing piece of hardware. And good luck with your NAS. I started with a D80 that i never really learned and Nas brought me to a D7000 and mired of lenses and gear i might not really need .
I'd focus on figuring out what Focus setting work for you. The 39 point AF is a marvel over anything that i had used. And maybe the same for you.
Also while Nas is brought up. Check out the thread on Grips to find out whether you may think you need one, and what maker might interest you. If you shot full bodied Film camera it might be the next step in improving your time with the D7000.
Welcome to our forum page. And please share some of you pics and thoughts on your new camera.
