Pentax 16-85mm zoom ring stuck, doesn't focus

On my vacation to Hawaii i decided to take along my 16-85mm. The lens worked well until the last evening of my trip (thank goodness it was the last evening otherwise I would've been maaaaad).
It stopped focusing AND the zoom ring stuck! I could not even manual focus!
Any idea what is causing this and around how much it is to repair?

Odd that both the zoom and the focus mechanisms were affected. It could be that a bushing broke off of one of them and got lodged in the other.

Were you in a very sandy area? You might have something stuck on the outside of the lens barrel between the two rings. Grab a magnifying glass and check carefully under good light.

Did a seal come loose and catch the lens barrel?

I had my 16-85 zoom mechanism break under warranty. It would start to zoom out and stop around the 35mm mark. It would then be locked up. You could then take the lens and turn it upside down, off the camera, and hear something inside click. The lens would then zoom again until upright. So, try turning yours around at odd angles and see if it frees up and then locks again. Mine was under warranty, and Precision sent it back to Pentax, saying they didn't have the ability to fix it here. The repair description was vague and sounded like an issue with the barrel assembly.
