Well, it seems that you do not have too. According to other users reports, in natural light K-r AF is the same like K-5.

I am wondering why Pentax does not try to introduce real ring motor in their lenses. Correct me if I am wrong, but this technology was introduced by Canon in 1987! It is more than 20 years ago... Current SDM solution is really poor and from my point of view it was a mistake - it has only one advantage (silent focusing). Pentax just spent a lot of money on something that is (amost) useless...
Even Sigma makes faster (in terms of AF) lenses than Pentax (like old screw-driven 100-300 f/4 or new hsm 24-70 f/2.8).
Generally this is one of two only issues in Pentax system. Second one, somewhat related to the other is lack of fast (in terms of aperture and AF) super-telephoto lenses (like Canon 100-400 L, 400mm, 500mm). For action (rallies, races, air shows, sports etc.) or wildlife shooters it would be nice addition to lens lineup (I know, I can switch to Canon, but I do not want to because of other Pentax features)
Besides these issues, Pentax is just PERFECT
