The amount of focus adjustment is controled by the camera. It has a senser which measures the amount needed through the lens (TTL).
The lens has the motors which actually move the lense into that focus position. So it depends on the camera wether or not a point is picked, and it depends on the lens how fast it actually gets there...

10d has alot faster focus than any other digatal camera - I think that statement needs qualifying ... it is faster than the D30/D60, and probably the D100. A 1Ds or 1D will leave it standing! It is basically the same system as Canon's mid-range EOS 30.
