Originally posted by Ant Thanks for all the advice - I see quite a few recommendations for the K-r but on looking at its review on the forum there appears to be a lot of AF issues with it.

Pentax tried upgrading the AF logic in the K-r and original K-5. The AF systems were slightly different but results were similar. Many users complained about AF errors, particularly in tungsten light. These issues were hard to nail down exactly, because focus is tricky anyway and in low light/low color temperatures, everything is working against perfect focus. The complaints died out after new cameras came out.
I bought my brother a used K-r at the height of the complaints and could not duplicate the problem. He hasn't seen it either in a couple of years use. So
my conclusion was that all cameras weren't affected to the same degree.
