That looks like a pretty wide angled shot with lots of depth of field
(I downloaded the full-sized and looked at the EXIF info - Focal length = 18mm, f/8, - and was the exposure time really -0.2 sec?)
I have often wondered about "
Predictive AF" -
where the camera uses algorithms to predict where the moving subject might be.
Predictive AF is touted to be useful for tracking fast moving subjects,
and could even help minimize moving out of focus during the shutter lag/delay
(eg: at 60mph - a lag of 0.10 sec, means the object would have moved 8.8ft!)
But this works only for linear or "predictable" motion - it doesn't work well for sudden or more random motion - like animals or kids.
(I don't think either the K100D (Super) or K10D has predictive AF).
BUT the point is plenty of sport photographers were very adapt/competent at capturing fast action using manual focus in the days before AF (and even auto exposure) ........
So there's a lot to be said about using pre-focus and adquate depth of field for capturing action.
Pre-focus by either turning the AF off -
or using AF and hold focus on pre-selected points of focus in the scene -
and using one's instincts/muscle memory to trip the shutter at the right time -
ie: the photographer now becomes the "predictive" engine -
and the photographer often is the more reliable "intelligence" over almost any automation.....
Relying on automation blindly without "intelligence" (understanding the limitations) -
would probably result in "unintelligent" results ....
of course, understanding the automation and using it with intelligence -
can be a very powerful combination
