DA* 16-50mm wierd backfocus at 50mm???

hi guys!

I found that my DA* 16-50 had some backfocus problem when shooting at 50mm f/2.8, and the focus distance longer than roughly 1 meter.

the problem does not exist if the object is within 1 meter. The focusing chart test is perfectly normal.

Did anybody experience this before? is there a way to fix this?

thanks a lot!
