    Basith, As i said before all the auto focus does is focus on the subject automatically, Manual you do it yourself by turning the focus ring to obtain focus. the camera takes the same picture whichever you use, It does not get any easier than.

    Obvously focus is very importent and both methods can give exactly the same results

    The motors that drive autofocus can be either in the camera body or in the lens. The traditional way was to have the focus motor in the camera body with the lens elements driven by the camera using a screw thread. It's becoming more common nowadays for lenses to have built-in focus motors (very small silent piezo-electric ones, called variously SSM, HSM, etc) in which case the in-camera motor isn't used. Some manufacturers (Nikon) have stopped putting AF motors in their cheaper camera bodies. This is fine if all your lenses are SSM, but if they're not then they have to be manually focused.
