Chris - Thanks for your reply. I think my issue is fundamental -- does the D800 produce better or equal images at high ISOs than the D700? Bravo Zulu (Navy-speak for "well done") for your answer: "Yes." It seems logical that Nikon would not produce a next generation camera that generated inferior images, but there has been so much talk that 36megapixels crammed into the same space as 12mp must generate more noise and therefore be less effective at high ISOs. Your and JRPs answers point to the D800 outperforming the D700. Much of my photography is in low light -- high school sports for a newspaper. So this is important to me. Again - thanks for joining the discussion. You are a typical Nikonian - priceless!
