Firmware updates for the Nikon D810 and D810A cameras are now available. Both updates fix a bug that may cause the cameras to stop responding if attached to a WR-R10 wireless remote control running firmware 3.00. The updates bring the Nikon D810 to firmware version 1.11, and the Nikon D810A to firmware version 1.01.
