I have just purchased a Nikon D40x/D3000/D5000/D3100/D5100 camera and the auto focus of my Sigma lens will not work with it. Is the lens faulty?

Unlike most cameras, the Nikon D40x/D3000/D5000/D3100/D5100 does not have an auto focus motor built into the camera. Therefore, auto focus will only work with our HSM lenses as these have a motor built into the lens.
