I still don't understand why Nikon would have a dual assembly line making the same products - one original and one gray.
This is the blurb from one seller. A camera is mentioned although the item advertised is a lens. They had the same blurb for both the import and the USA model. Go figure!
Note: This Nikon camera is a parallel import. It is identical to the USA model and is likely produced by the same factories. This product comes set in English as a standard language, with USA connections and English manuals. Imported models usually do not carry a USA manufacturer warranty card.
