AF trouble with K5 and old and new DA 50-200mm ED Lenses

Recently I had a problem with my new K5 and DA 50-200mm ED Lenses (I have two of them). After putting this lens on the K5, the camera used to struggle to adjust AF and give out a continuous sound as an indicator. I found this out after trying all the other lenses first. It only occured with that lens. The problem is that when you put the lens on, you twist it until it stops,then you have the problem. The trick is to give it a little backward turn to make it click, then everything is OK! I have no such problem with my K20D though.
I just wanted to post this to save people from distress.
Kind regards, Nezih
