Autofocus is great, spot mode for still images, continuous mode for moving subjests easy??? Ok most of the time for still images spot or local (selected focus point) is great. Moving subjects not so much, if you know your subject is moving in a predetermind line like motor racing, cycle racing, running well you get the idea, continuous mode will track it without any trouble, other sports like rugby, football ect. and wildlife do not follow set paths, so you loose focus find your subject again then you lens refocuses but this all takes time. Manual focus does not "hunt" so with a little practice it will be faster than continuous mode. Soon you,ll never miss that crucial shot. Practice on still life take you shot on auto focus then refocus in manual mode you might be surprised by the results.
