K1 wont focus at infinity

When shooting the k1 with the pentax 16-45 lens, the camera sometimes will auto focus the lens. I really notice it when i stop down the lens to f11 and
focus at infinity.

The first thing is: have you updated your firmware? The latest K-01 firmware has improved the AF.

Second, do you have the problem in low light? In the affirmative, it is normal: the AF of the K-01 is not at best in low light/

Third, as suggested by Primes4ever, it may be the lens which does not pair well with the body. With my K-01, I found that the small light lenses works best (eg DA40mm, DA 15mm). Some zoom lenses do not work well (eg DA18-250mm) in AF. In these situations, you can always use MF.

Hope that the comment may help.

Can you try the lens with a different camera?
Can you focus to infinity if you use MF (manual focus)?
