My K-1 also froze with Sigma 24-70 HSM.
So the solution is to call Sigma customer service?
Just because that lens was on it doesn't mean it is the lens at fault though. FWIW, both my K3 and my K1 experience
extremely rare but occasional lock ups. Usually to the point of needing to pull the batteries, sometimes it will correct after power down (although the power down takes a long time).
This is with a variety of lenses, and I do not use the 24-70 on the K3.
