It's a long shot, but I suppose it's not a zero probability. I did buy them from my usual authorized reseller, a brick and mortar place that I trust implicitly. I observe that this happens ONLY in very bizarre circumstances, and it is really quite difficult to track down - I've had my D3 and these lenses for over three years and have only just been able to converge on the trigger circumstances. So it seems to me that the likely case is that these are real ones.
BUT having said that, how do I validate these? They have serial numbers on them, I guess I could try to ask SanDisk about them. Is there any more sophisticated way to do this?
