I have experienced the same situation. The lens seems to be good so far. There is some stickness (a little) near 28mm. I bought this lens from B&H. My previous one from Abes Of Maine was bad and I had to return it. The serial number is
9025709
One thing I noted is this serial number seems to be from the 2008 batch and my previous 16-50 got from Abes was 2007 batch..
