Re: DA* 16-50mm SDM failure.... finally happened to me..

My 50-135mm just had its 3rd birthday on the 3rd of this month. It had some erratic behavior from years 1 through 2 if I left it some weeks without using it. It would take a while to wake up and start focusing. But since year 2, I haven't had anymore trouble.

My 16-50mm will be 3 years old on july. I haven't had any trouble, yet. Both are my workhorses, and I've shot at least 40K pictures with both.
