70-200 Focus speed

I'm currently shooting with a K3 and the Sigma 70-200mm f/2.8 EX DG APO OS HSM but I really want the WR of the Pentax lens, has anyone been able to see the difference in focus speed between the 2 lenses?

Thank you in advance.

We've got some timings here, which you could compare to your copy:
HD Pentax-D FA* 70-200mm F2.8 ED DC AW Review - Focusing | PentaxForums.com Reviews

I've used both lenses, but not at the same time. Subjectively, I would expect the focusing speed to be about the same with both lenses.

Thanks Adam, I will look at my Sigma against the video, I'm not really looking for lightning speed, as long as the speed is close, I really just need it for the WR

Haven't used Sigma, but I have 70-200 DFA*. It is fast.and focus limiter makes it even more fast.

The Sigma 70-200 is one of the few lenses I haven't used, but the Pentax 70-200 is one of the fastest Pentax lenses I've used. It should be on par, or faster, than the Sigma, and add the WR you are looking for.

Oh! And its IQ is possibly the best I've seen. Close, anyway.

Thanks for the replies, I did a lousy test with the video Adam posted, I'm using a K3 but the speed seems to be pretty close, I will have to ring up B&H in a few days.
