Pentax 18-135 Lens Focus through Zoom Range

Hopefully just a quick question. I have the Pentax 18-135mm DA Lens. Should it maintain the focus through the zoom range or should I have to re-focus as I zoom in or out? I know on some zoom lenses once you focus you can zoom in or out and it will maintain focus. On this lens I have to focus every time I change the zoom range. Is that normal?

Thanks
