This past week I was in Europe, in Germany and the Netherlands. Thursday I was stuck inside all day due to rain, but after dinner the rain let up and I went out with my camera and the very nice (and relatively inexpensive) Tokina AF 12-24mm f/4 AT-X 124 Pro DX II Lens. This is about half the price ($495) of the Nikon equivalent and is a solid, great performing lens. The challenge I set for myself was to just use this lens, no switching, forcing me to think in wide angle terms. The f4 setting let in a fair amount of light and the D7000 range resulted in (I think) decent photos.
