The autofocus system is simply looking at the focus and deciding to change focus in one direction or the other, and repeat until the image is in focus. There can be problems relating to the camera as it requires that the autofocus and image sensors are in the same optical position.<br /><br />There can be focus problems related to lenses, for example, curvature of the focus plane but these are focus not autofocus problems.<br /><br />Maybe some one has an explanation of why.Kennoreply@blogger.com
