I've uploaded a lot of pictures from Iceland, but I've not yet done any technical work on any of the ones of interest: check them out.
I'll hope to have some commentary here eventually. I will say that the d7000 earned its stripes here, and the 70-300 was a good tool to have for some of the wildlife shooting. Continuous AF and reasonably snappy AF-S motor did a good job on several different shots.
The 28mm was the most commonly used lens on the trip; I was repeatedly disappointed that I didn't have anything wider, but I made do well enough with what was there.
