New K20D - Focus problems

Just got a K20D. Several test shots taken with 4 different lenses. All lenses worked fine and are sharp on K10D.

On the K20D, one lens needs -10 AF adjustment. One needs +3. and the other two are fairly sharp without adjustment.

Not really sure what to make of it. If all were out, I would say a bad body. However, since they are mixed, I'm not sure.

My main concern is the one needing -10. No way should it be that far out when it is sharp on the K10D.

Any suggestions? I hate to send it back with the holidays. However, I don't want to be stuck with a bad copy.

No real need to send it back. I have several friends in the same boat as you are. Lens worked fine on K10D, needs adjustments on K20D.

Thus my reluctance to get the K20D, to date.

I spoke with Pentax and they agree something is not right. They suggested I exchange it.

We will see. If the replacement does the same, I will just have to live with it. I will most likely end up sending the lens needing the most adjustment in for a checkup.
