When testing with the focus test charts you must use a tripod and daylight. Artificial light will give you false results.
However, looking at your outside shots you may indeed have back focus. I recently got this lens and it is very accurate on AF, although can be a bit slow to achieve focus. I use a split-prism focus screen and can see that I am getting 100% success with the AF. Do some more tests and if you continue to get consistent BF get the lens exchanged.
You can do in camera AF adjustment with the K10, with firmware earlier than 1.3 It is still possible with 1.3 firmware but you have to use a hack. However it will affect all lenses and if you have no issues with other lenses this is not the route to follow.
I was concerned before I bought the lens but early results for me show it to be a cracker.

RR , i see the point you are making about the top bar going out of shot while still in sharp focus, and I think you are right, a fade-out would be better.
Martin, I am not sure if a closer image would be better , or just different. But the place is not far from where I live and I will go back and try to produce some different ideas.
This is why i love this forum. What I suddenly think is a great shot, can possibly be made better.
Thank you.

I'm using AF center point. I made sure I had the hexagon confirm a lock and I had AF with remote turned off in the menu so clicking the remote would not trigger another AF.
