i can't explain why the upper part is tilted. i suppose it has something to do with the angle i was holding the camera and distortion from the lens (maybe?) as for getting a D200, its a great choice for a camera. i personally use a Nikkor 17-55mm F2.8 and a 70-200mm F2.8 VR. these are great lenses, however they are expensive. sigma and tokina make nice alternatives, but if you can afford it, get Nikon glass!
