Updated firmware for the Nikon D800 has been released this week which addresses many features and issues with the Nikon D800 and D800E cameras. This firmware update adds a the ability to reprogram the remote function button. Additional functionality has been added when using the UT-1 communication unit (with updated firmware 2.0) allowing the camera to function as a HTTP server. The camera now supports Compact Flash (CF) cards greater than 128GB. The function of the AF-ON button now allows for a “focus trap” to be set so that the camera will take a photograph when a subject comes into focus on the selected focus point. Occasional hangs that caused the memory card access lamp remain lit for an unusually long period of time causing the camera to not respond have been fixed.

The updates require a Windows PC with Windows 7, Windows 8 or Vista or a Macintosh computer with Mac OS 10.6.8 – 10.9.2. The installer will extra a .bin file to your computer, which then needs to be copied to the top level of a media card (CF or SD). The new firmware can then be installed on the camera.
