I know. I photograph running and playing dogs almost every day. A

image. If you don't even shoot, just watch the image through the
finder, you
can see that the camera focuses, stops, focuses, stops, etc.,
sometimes
catching up, and never predicting the location of the subject soon
enough to
actually allow the shutter to trip when it arrives.
It's a travesty.
You might appreciate this little 7D test video:

I haven't even fantasized about autofocus that works that well. I can
see that if I were to start photographing fast moving objects then
there is definitely something a lot better than Pentax.
