while a K mount it is not built for a pentax camera, the distance to the sensor/film is incorrect.
however, since this is a very simple lens (in terms of construction) you can fix this problem rather easily with a set of minature screwdrivers, a clean workspace and lens cleaning tools since you probably will get a few things dirty unless your hands happen to not emit bodily oil.
you need to take the lens apart, and re-align the focusing barrel so that it moves lower than it currently does, then you will be able to focus to infinity.
however gettting it PERFECT is very difficult, so chances are you will end up with a lens that will focus to infinity, but also be able to focus PAST infinity! so you would have to be careful
best results are with a split primsim focusing screen so that you know when to catch yourself.
