Really cannot understand why people get their knickers in a twist over gray market ? save yourself some money buy a nice lens and buy gray . No problem - I dislike restrictive practices . Truth of the matter is with a 'good' gray importer you get a better warranty - most things go wrong fairly quickly and you will most likely get a new camera. Don't forget the golden rule of big companies IS IT WARRANTY OR POLICY - you will find that EVEN in the US Policy claims (like recalls) will be honoured by most major manufacturers. Ralph Nader may help you although not sure what he would charge these days.

Nikon and it's authorized dealers will NOT repair gray market equipment - period. Your only options are independent repair guys, and whatever parts they can get through their channels. The only way you can get a camera repaired in or out of warranty that came from a different market is to produce a bill of sale from a retailer in the country of origin that resulted from a face-to-face transaction. Otherwise it is considered gray and Nikon won't touch it.

In 2013 Nikon pulled support from the independent repair network - no manuals, no tools, no training, no parts, no support. If you have a gray market camera pray that it doesn't break.
