K-01 and sigma 18-125 f3.8-5.6 hsm

Has anyone tried this lens with the hsm drive in the k-01? Does it focus accurately? How well do HSM motors do on a k-01?

Thanks

do not have this lens any more but it was replaced with the Sigma 18-250 Macro HSM and I also have Sigma C 17-70 Macro HSM both working very well with K-01.
the only focusing problem on K-01 I can experience is with some screw AF drives like DA35 Macro Limited or D FA 100 Macro WR

I have trouble with my sigma 17-70 2-4.5 dc on my k-01 but it works great on my pentax k20ds and k30. I'm hoping the 18-125 with hsm works better on the k01. Seems like yours with hsm motors work well.

Is yours the hsm type? Is the problem misfocusing?

Is this with the latest firmware, since there where improvements in AF with newer firmware's.

I just received the lens and popped it on the K-01. The few shots I took looked sharp on the LCD even upon magnification. Looks like it might be a workable combination. (But, it was a very limited test.)
