In a recent thread, http://forums.dpreview.com/forums/read.asp?forum=1036&message=36445031 , it says that Sigma HSM is inconsistent on the new Pentax K-5. Maybe we should start a new thread about this specific matter.

My experience with Sigma HSM on my K10D and K-x is that the behavior is similar to Pentax SDM. Perhaps the new faster SAFOX IX system in the K-5 and K-r requires update of Sigma HSM? This is bad news for Sigma users, even though I believe Sigma will offer this for free if it is needed. But if this is the case, one needs to send the Sigma lens in to Sigma distributor for replacement of the internal chip.
