Early days yet, though so far I can find no fault with my D200. "Out of the box" images are admittedly a bit soft, but that is what unprocessed digital images are like - Bayer anti-aliasing filters are not sharpness friendly. This is easily compensated for in camera (if you wish) by setting sharpening to high or out of camera - assuming you are shooting in NEF or NEF + jpg - in Capture NX or Photoshop. I am NOT going to complain that Nikon do not mess about with the image before I can get at it!
I have been using a Fuji S2Pro for the last 4 or 5 years and still think it is a fantastic camera. But the D200 leaves it standing. Truly awe inspiring performance. Don't hesitate, buy one now! I see many other reviewers have commented adversely on the D200's battery performance. I don't know what they have been doing but I am astonished by how LONG the battery lasts - hundreds and hundreds and hundreds of exposures. I have not yet managed to flatten one in a full day of shooting without flash, and that seems good enough to me.
Any specific queries on my experience with the D200, send me an e-mail.
