He's pining for the Fjords !
All yes as far as I am aware.
Manual focus needs good eyesight - thats the only thing I can think of
Tamron has a screw drive Af system, wont Af with D40, not sure about D40x.

Same with the D40X, Rob.
Guerrero, just to expand on what Rob says, the D40 and the D40X have no motor inside the camera to drive the auto focus in most lenses.
This means that only Nikon's AF-S lenses (which have their own internal AF motors) and some Sigmas (those with HSM drives, and the 80-400mm OS which has a built-in motor, though not HSM - this might also be true of the 18-200mm OS, but I've struggled to find out) will auto focus.

You can read a description of the Nikon AF lens situation on Popular Photography's website. Must reading for D40 and D40x owners!

There you go then - the 18-200 isn't on the list.
