Nikon releases service advisory for their D810 digital SLROn Tuesday, Nikon USA added a service advisory for their new flagship HD-SLR, the D810. The advisory, which can be found here, notes that some D810 users are experiencing odd noise in their long exposures, which consist of bright white spots in photos. This phenomenon seems to occur when using either slow shutter speeds or the 1.2x (30x20) Image area setting.
Nikon is offering a repair service free of charge for any affected cameras that may have been sold. To see if your camera is included in this advisory, you can check your serial number by clicking here.
