In the Uk Nikon only give a 1 year warranty, If you register your camera within 1 month you get an extra 2nd year warranty. This warranty only applies to the original owner and is not transferable. However Nikon Uk are now offering a third year warranty coupled with Domestic and General Insurance Company. The warranty also covers accidental damage insurance world wide and because it is an insurance policy it is transferable to a second owner.
I took the policy out on my pro camera bodies not just for the accidental cover, but though it would help the value of the camera if I sold them in the 3 year period.
