Honey, you can not compare D40 and D200 as they're designed for diffrent segment.
we can say technically D200 is more like D2x (pro camera on nikon Line) and designed for serious-amateur while D40 is designed for entry-level. (D200 is one year older than D40)
The biggest negative of D40 is that this camera doesn't have internal "focus motor" on it's body. Lens focusing only available with nikon AFS-AFI lenses (Lens with internal motor focus).
in other words, you have to have AFS or AFI lenses to use autofocus.
