Update,
Within 7 working days I received my 100-400mm lens back from Fuji NJ.
There was an invoice that said my lens has a new seral #. They did'n't say what was wrong with the lens.
So they sent me a replacement lens and it works great.
Now after 3 weeks of use my new X pro 2 freezes up . It happened 5 times yesterday on a 6 hr. shoot.I had to keep taking the battery out and replacing it back into the camera
I guess I better send it back to B&H for a new replacement before my 30 days are up .
Otherwise I will have to pay for shipping and insurance to send it to Fuji in NJ.
