I don't know the story regarding that particular lens. But Nikon has been manufacturing lenses in China and Thailand for some time now. I know, for example, that the current 50mm. f1.8 AF lens is made in China. I'm guessing that others are, as well.
I also know of no particular evidence that items made in Nikon factories in non-Japanese countries are inferior in any way to those actually made in Japan. I'm sure someone will contradict me here.
In the meantime, I am inferring that a large part of your concern is that you have received a bootleg/knockoff copy of a Nikon lens. This seems very unlikely, but hey, anything's possible. Is there anything in the way it's assembled or finished that would lead you to believe this?
