I currently have three lenses, the Nikkor 18-200mmVRII, the 18-55mmVR, and the 35mm/1.8. I also have a Nikon D3000.
In one week, I will pick up my D7000 and I believe that if the bottom fell out of everything, the D7000 and those lenses would do me well. In fact, the D3000 would do me well, but I expect the D7000 to do me better.
I've only read reviews of the D7000, but based on the good and the bad news a la the "experts," I expect to be thrilled to death.
I also expect that I will add one longer and one wider zoom, although I don't know what they will be, as yet.
So, in keeping with the intent of the thread, the set up listed is one I could live with quite easily.
