<Interesting, I've never used one of those. But wouldn't Nikon have done their calibration in some other way? Usually cameras come with a single digit number of frames on them, or at least they have in the past.>
I'm not sure, but there was a recent report of a camera coming back from Nikon Service with about 1200 shutter activations. Since the test product is relatively new, it would not surprise me that Nikon has a more advanced program used for quality control or service. We've had earlier reports of other "new cameras" showing up with shutter activations and dismissed it as an open package or a return. There may have been a different reason.
The good new is that if the camera AF was tested as a production sample, there would be no AF issues. I would willingly submit my future new camera body or lens to such a test.
