You're forgetting the third possibility. I just got my K-7 today, and put on the DA*60-250 and the DA*16-50 I'd got about a week ago in anticipation of the K-7, and took both lenses out for a very brief spin. I'll have to conduct some in-depth tests to check for various issues, but, regarding focus, both did A-OK. Of course, these are slow lenses (F2.8 and F4) so I won't have to be as anal as I would be with my faster lenses (F1.2-1.8).
Of course all companies have QA issues, and Pentax/Hoya has been slammed for the 16-50mm, so you can't rule that out, but I doubt both your star lenses could be at fault, especially if they're giving you similar faulty results.
So, if it's not the camera's fault (AF sensor having backfocus), well, mate, the only other explanation
is the third possibility.
And, I'm sorry to say, taking hundreds of pictures a week, and even getting paid for them末i.e., making you a "pro" in that sense of the word末doesn't make you an expert. I know of plenty of "pro" photographers who are less knowledgable about their gear than I am, someone who just started shooting DSLRs exactly one year ago. You may not be a troll, and I'm sorry for calling you one if that's the case, but the attitude you come in with末that the problem must lie with the star lenses and
maybe the camera, but
no way can it be your fault... well, let's just say, it doesn't gain respect from me.
