A professional tool or an aid for the amateur?

摘要

Will Auto Focus add the value to broadcast that it has to still photography? You only have to look at still sports and action shots of recent years to see the difference that Auto Focus techniques have made. There are far more professional shots where the moving object remains in perfect focus - a football flying into the net, a tennis player hurdling it: and how often now do we see pictures of birds in flight, every feather in total clarity, in a way that would have been very lucky, or technically extremely difficult, a few years ago? Auto Focus, at first rejected as a crutch for the amateur photographer, has become accepted as a valuable professional tool in certain situations.
