O.K., I probably should have done more research and spoke up right after I purchased the camera back in Aug 2006. I'm thinking of upgrading from my D50 to possibly a D80. I might sell it on Ebay with some accessories. My question is, how do I determine if I have a grey market or not. I purchased on Ebay from panwebi (Soho Electronics-NY). I thought that I paid a resonable price for all that was in the auction. I have researched and researched and cannot tell if I got grey market. I look at the D50 label on the side of the box and see lots of japanese and by the upc code it indicateds D50 (J) BK. The D50 manual itself is all in English. I think that when I originally turned the power on back in Aug 2006, it was set to Japanese and my first thought was that I purhased a grey model. I did purchase a 5 yr Mack Extended Warranty, but I only wanted to protect my investment. I just do not know what ot say or list if anyone asks if this is a grey model or will they even care if I add in the 5 yr Mack warranty, which I did check and can be moved over to the knew owner for $15.00. Please provide feedback, Thanks
