The D40x does not have an autofocus motor, and neither does the AF NIKKOR
50mm f/1.8D. Therefore, your D40x will not be able to autofocus with the lens.
Also, please be aware that all our 50mm lenses are FX lenses. Using one on the D40x, which is a DX format Camera, will give you an angle of view of about 75mm when compare to a 35mm film camera, or one of our FX camera bodies, due to the 1.5x DX/FX factor. An AF-S DX lens would be more suitable for the D40x. Unless you are going to be upgrading to an FX camera soon, You may get one the 50mm AF-S lenses. If not, We recommend the AF-S DX NIKKOR 35mm f/1.8G.
