K20 and USM lenses

I purshased a new K20 earlier this year and recently discovered that it will not Auto Focus USM lenses. I have only used Pentax lenses to date, however due to this problem the camera is not resellabe or tradeable to upgrade to a K7 should I desire to. What can be done to correct this problem?

As far as I know, USM lenses are made by Canon. I took a chance you may have been referring to Sigma HSM lenses and called them. They said their HSM technology is compatible with the K20. I would have the body checked to make sure it is working 100%.

Chuck, can I come by tomorrow to try out the sigma 18-150 HSM? Do you have a sample of that in stock for Pentax?

I believe OP was referring to Pentax SDM lenses.

Yes, we have the lens in stock. You can ask a salesman at the Photo counter to help you.
