Capt Chad, you will have no trouble with a standard tokina 10-17 lens with the D7000, which I use as well. The D7000 is a DX camera and the lens is designed for such a camera. You can also use domes in the 4 inch sizing with that setup. There are several mfg companies with small domes for that lens and camera setup. Its quite compact for travel and very nice for close focus wide angle. The lens will focus all the way down to the dome.
