Sigma 120-400mm f4.5-5.6 APO DG OS Anyone?

Does somebody have experience with the new Sigma 120-400mm f4.5-5.6 APO DG OS?

I've a few questions:
- How does it hold at the long end, sharpness?
- AF in low light with K-7, any experiences?
- How effective is the Sigma OS compared to the in camera SR?

I'm needing longer quality glass than my DA* 60-250mm....
