There is a firmware update for Nikon D800/D800E and D600:
D800 and D800E:
http://support.nikonusa.com/app/answ.../18257/kw/D800
Supposedly addresses the following, according to Nikon:
Support for the AF-S NIKKOR 800mm f/5.6E FL ED VR has been added.
Subject tracking performance in AF-C (continuous-servo autofocus) autofocus mode with framing using the viewfinder has been improved.
Gamut for Adobe RGB images displayed in the camera's monitor has been changed. This enables more vivid display of images.
With live view photography in [M] (Manual) exposure mode, exposure preview was always on. This issue has been resolved.
In some very rare cases when certain memory cards were used, movie recording would stop, even when the time remaining display indicated remaining recording time. This issue has been resolved.
With shooting at an image quality setting of TIFF (RGB) and an image size setting of Small, the right edge of images contained a purple line. This issue has been resolved.
In some rare cases, images recorded in JPEG format could not be opened by some software applications. This issue has been resolved.
In some very rare cases, colors would change with shooting when white balance was set to a specific color temperature, as with Preset manual or Choose color temp. This issue has been resolved.
D600:
http://support.nikonusa.com/app/answ.../18267/kw/D600
Supposedly addresses the following for the D600:
Support for the AF-S NIKKOR 800mm f/5.6E FL ED VR has been added.
Subject tracking performance in AF-C (continuous-servo autofocus) autofocus mode with framing using the viewfinder has been improved.
Frame output size has been changed from 95% to 100% when movie live view display is changed to "Information off" and an HDMI-compatible device is connected.
An issue that caused the right edges of images to be somewhat white when captured at an Image area setting of DX (24x16) 1.5x with Active D-Lighting set to Off has been resolved.
When the camera's shutter-release button was pressed repeatedly for uninterrupted shooting with the "Record to:" option in Camera Control Pro 2's Storage tab set to "PC+CARD", the camera would stop responding with displaying "Err" in its control panel. This issue has been resolved.
In some very rare cases, colors would change with shooting when white balance was set to a specific color temperature, as with Preset manual or Choose color temp. This issue has been resolved.
I'm glad they added support on the D800/E for the 800mm f5.6
