The K10D demonstrates approximately the same levels of detail as the EOS 40D but simply isn't as sharp, at first glance it really looks as though the K10D image isn't properly in focus but as you will see on subsequent comparison pages the detail really is there it's simply that the camera's built-in image processor isn't extracting the detail (or is destroying it with heavy-handed noise reduction).
