The good people at Nikon have sent me a D500 to review.  While it has been in market since the spring, they are very popular and demo units have been scarce.  I received it in a kit form that included the 16-80/2.8-4 zoom lens.  I also received an SB-5000 speedlight and wireless radio kit as I think that the interaction with a speedlight will be important to serious amateurs and pros.
