50-135mm f2.8 Auto Focus goes to sleep?

I have the 50-135mm f2.8 lens. I love it. However, I've noticed that if I don't use it for a couple of weeks, the auto-focus seems to not want to work for the first few minutes of use. After a couple of minutes, it works like a champ.

Is this a defect, or do others have this issue?

Oh dear.
It has been mentioned quite a number of times, and many in the last few days...

I have exactly the same - ever since it was bought new. And so do many others. It seems to be a prelude to complete SDM failure, but I guess we can live in hope.
