I suspect both suffered from poor packing for the transit as they were just sitting on one side of the box w/o protection at all. The lens was eventually sent to Japan for service but came back the same. I stripped it down recently and found nothing to be re-adjusted really but that the last 2 lens groups wobble when departed from 16mm. I believe it is this wobbleness that causes the BF as well as blurry pictures at 45mm (when shooting vertically, my copy at least). IMHO, if you can still exchange, do it. I am not optimistic that the service centre would be able to repair it.
So your second lens is better?
