Hello guys! I just want to ask if all Nikon Lenses come with a serial number on it? I just bought two lenses (85mm 1.4D and 50mm 1.4) over the internet and it came in a few days time from Hong Kong (where most bargains come from anyway). When I looked at the lenses, I noticed that there was no serial number on either lens? Now, I'm thinking if these lenses are legitimate Nikon lenses.

Does anyone have the same situation? Or, if anyone can shed some light so that I won't feel "troubled" with my newly bought lens, I would really appreciate it.

Thanks, in advance!
