Which seems consistent with stevebrot's meaning.
After buying K-3, I was not able to get as many sharp photos as I was with K-5 II. So I did some testing and found K-3 to be a lot worser than K-5 II regarding precision on screw driven AF lenses with long focal lengths. (That is 200mm +++). With SDM lenses the precision is very good on K-3, but unfortunately older lenses sucks big time.
I am not sure at this time if this is a problem with only my own K-3 or if it is a common problem. I will do some more testing with another K-3, but it would also be interesting to hear from others who have seens similar behaviour.
