Testing noise for ISO 3200 and ISO 5000. Here's a link to the photo gallery. Just a random, quick, unscientific test. I think the noise level is controlled very well. I would say that the D700's noise level at 3200 ISO is about the same or perhaps even lower than what the D80 produces at 1600 ISO. Hope to add some samples of pix shot at 6400 ISO in the near future.
