Wow, well you've convinced me! Any PP on either of those images?For me the D300 is a much better camera than the D200 (which is an excellent and very capable body in its own right), noise handling and the superb new AF are the two most important points for me.
I got mine just before Christmas and this was one of the first pics straight out of the box with default settings.
ISO 1000....
And a 100% crop of the same image....
Great.With the first shot I enhanced the eyes to give them a bit more pop but everything else is as it was shot - exposure, colour etc and just resized and sharpened for web.
The second shot has had no pp except for resize and sharpen, lighting was just the stage lights iirc. Both taken using the 17-55mm f/2.8.
