On August 19, 2014, Nikon acknowledged a problem reported by some users, of bright spots appearing in long-exposure photographs as well as "in some images captured at an Image area setting of 1.2x (30x20)." Existing owners of D810 cameras were asked to visit a website to determine whether their camera could be affected, on the basis of serial numbers. Repairs would be made by Nikon free of charge. If bright spots still appear in images after servicing, Nikon recommends enabling Long exposure NR. Products already serviced have a black dot inside the tripod socket.
