Do you use Sensor OS or Lens OS or Both

all first party pentax lenses have no stabilisation so when using pentax lenses, have to use in-body shake reduction.
lens OS is only available with newer 3rd party lenses (i.e. sigma) and you can't use both. either the body or the lens stabilization has to be switched off.

Aah ... I just found something interesting from Dpreview : For Sony and Pentax mount, the built-in OS function of this lens can be used even if the camera body is equipped with an image sensor shift anti-shake system. As compensation for camera shake is visible in the viewfinder, the photographer can easily check for accurate focus and ensure there is no subject movement. To be honest I am quite skeptical about this statement. If both OS can give me 2 stops, then add together I get 4 stops ?

No. You use one or the other.
You should only use one at a time - there is no way for the lens stabilization and in the in body stabilization to communicate with each other.
If you have shaky hands and if you are using a long lens, then its nice to make use of the in lens stabilization as the view thru the viewfinder will become stabilized also.

Yes. Its not wrong to say this but they did not elaborate further. Lenses with SR (shake reduction - that's the pentaxian lingo for image stabilization) can be used on cameras with sensor shift but the sensor shift need to be switched off when using these lenses.
