So. Since many here are testing the D700 out. How do you compare ISO noise with your old D300? I know it's very hard without a stringent testing platform, but off the top of your head at would you say? ISO 800 is fairly easy to get a decent looking shot with the D300. What is the "ease" factor with the D700? Is there a big advantage at ISO 800? Or even 400? Or for that matter, how about base ISO(low)? Thanks.
