Sigma 30mm QA/QC?

Dear All
I just received my Sigmas yesterday. The 30mm, when shaken gently, feels like something inside it is not secured. Not like there is a screw loose, but perhaps the whole glass assembly wobbles.
That is not the case with the 19mm.
Is the 30 supposed to be like that?
thanks
Christos
