Looks to me as a legacy bit of buggy remediation code that was never fixed and may not even be required in the k3.

If it is simply a bug in the firmware, Pentax should have nailed it long time ago. I think it is more of a hardware design problem. Very possibly the power analog circuit design if I would venture a guess. All Pentax DSLRs seems to be very sensitive to battery ever since *ist days when off-the-shelf AA batteries were used. I believe Pentax must have looked in that direction hard and that is probably why Pentax later went with " proprietary" batteries for K-series - to have a better control of battery quality. When I bought my first DSLR, the AA battery flexibility was one factor that drove me towards Pentax. Not any more, sorry to say that.

I did think it was most likely just a firmware issue and rather hoped that was the cause. However the evidence of other people having never seen the fault started to mount, until GoremanX (who had never had the fault) attempted to reproduce it. He used the same settings as I had used to reproduce the fault, but on his camera no fault was triggered in 15000 frames.

So it seems that not all K-3 bodies are susceptible to this fault condition. The evidence does not seem to support any conditions having influence over how likely it is for the fault to occur, so I don't think I'll speculate on the possible causes any more.
