No one is saying the K-5 can't take great low light pics. In fact the K-5 is the best low light APS-C camera ever IMO. I would go fuirther to say the K-5 is huge leap forward for Pentax. It's a wonderful camera. I love mine to bits and I'm planning to buy a second one as I like to carry two bodies on serious shoots to avoid missing shots while changing lenses. i'm going to sell my K20 and K10 to fund this.
Those shots you posted are great. Shots that ain't easy to get using previous bodies. But they don't mean anything in regards to proving or disproving the low light AF problems.
Look, we can 'manual focus', or 'Live view AF focus' a low light shot with the K-5 and get it sharp. I've shot hundreds like this already, I'm particularly into urban street light shooting.
But the fact remains that there is a fault with a significant amount of K-5s which are Front focussing in low light. My K-5 is affected and I'm waiting for a fix. You can see the examples I posted earlier in the thread - the car license plate shots. My K20D has no problem focussing in the same conditions. I expect the same or better with my K-5.
