Dopes anyone have a complete, up to date list of Nikon firmware for the D800? I am unclear that Nikon USA currently lists all of the updates as there appears to be more than what they list based on what I was able to google. Also the instructions for downloading the firmware is baffling on the Nikon site. Is it a 2 step process? First download it to your computer and then to the camera? Obviously I'm a virgin.
