Well I'm surprised that you can't see what's wrong with it, it's plainly obvious . . .
. . . nothing.
May we know which lens it is? It may be one that has known issues that somebody might no of.
Is it maybe a zoom that suffers from barrel creep, that is, it changes focus when pointed up or down?
Does it rattle when you shake it?
No, it doesn't rattle.
The lens is a DA* 16-50. Apparently it tends to be out of focus in the top right hand side. It seems to me that its only aperture that's creating the out of focus area. Perhaps the guy that sold it has a problem with part of the sensor in his k5.
I also took a variety of square on shots of a brick wall and couldn't see any out of focus areas there either.
Hopefully, now I've mentioned where the problem supposedly lies, you still won't be able to see a problem.
Cheers

I took the following shots this morning, hand held. I didnt worry too much about composition etc... I just wanted to take a variety of different shots to see if the problem would show.
Can any of you knowledgeable people point out the problem, because im struggling to see it. Please dont hesitate in telling me I must be blind, because I would like to get it sorted.
Thanks Everyone!!
