I was in Las Vegas for CES 2011. While there I took my new D7000 to shoot some photos of casinos and hotels. D7000 has very good high-ISO performance. At ISO 1100 this photo still shows no noticeable noise. I have tested this camera a fair bit and images with ISO 6400 are quite usable. Shot with Nikon D7000 and Nikon 10-24mm lens.
Focal length: 10mm
Shutter Speed: 1/30s
