Originally posted by talgarik Some of y'all may be surprised by this, but people took sports/action photos for decades before cameras had any AF system at all. It's still possible to take outstanding photos without an AF system, and acting as if it's suddenly impossible to shoot action photos without one is disingenuous and insulting to the generations of photographers who have done so.
Surprisingly enough, the various improvements in cameras over the decades has led to some changes in photography styles across all genres of photography.
It's possible to shoot a football game (soccer, rugby or North american) with a speed graphic, but its a pretty safe bet that it won't be catching a lot the stuff that a high end digital ILC with a super tele will be able to get with ease.
I shot high school football and fencing with fully manual 35mm slrs and 50mm lenses. I got some good stuff, but the guys from the newspaper with their telephoto lenses and motor drives almost always got more and better action shots.
I did well shooting fencing. It required good timing, and not much else.
Sometimes the motor drive/ burst exposure gives a picture from slightly before the peak, or slightly after. More fps helps, but pushing the button at the right time is best.
AF has opened a lot of doors in the action photos genre.
