Yes, though there is some disagreement about how well. To work properly, it needs to have its firmware updated by Sigma to match the latest K10D firmware. Even then, mine delivers somewhat inconsistent results.
If I had it to do over again, I would have saved my pennies, waited a few months, and bought the Pentax 540.
