Focus barrel of my 21mm Limited is not smooth


Anyone who owns a Pentax smc 21mm Limited f/3.2 pancake lens knows that the focus ring rotates very smoothly.
Today I take my K20 out of the bag and I realized that the focusing ring had was making a slight noise and was sticking, as if there was a grain of sand inside.
It is brand new so I do not understand. It was fine for the last few weeks though.

Did anyone have the same problem with that lens?

Thank you!

I don't have the lens but I would Send / take it back for exchange if it's new. I wouldn't even waste the time trying to troubleshoot it.
