I don't own the 18-50, and I can't say exactly how fast the focus is in numbers, but what I can say that it is fast enough that I am not at all thinking about focus speed. Here is just one BBall example in a dark gym, and this was with my k10d (which has a weaker AF motor than the k20d). AF-C, (which was correcting like mad due to the action.) These players are as close as you can get to an all-out sprint in basketball.
