So did you get something back from repair, Woody? If so, how did it go?
D500 back from Nikon and shutter replaced for $308. Everything cleaned and all functions checked while it was there, and a new hand grip. About 3 weeks from the day I mailed until I got it back. Everything working great.
When I sent my 200-500 in for VR problems, they turned it around quicker, likely due to the time of year. That was a warranty repair and the lens is working well.
