Have you tried to tether a D4 or D800 to Lightroom? If so, you've learned that neither program can actually recognize these cameras. Apparently Nikon has yet to release the developer kit necessary to make this happen. Erica Barker points out that you can use Nikon's software "Camera Control Pro 2" to tether your camera to a computer, and then simply point Lightroom to that folder. It's an acceptable fix while we wait for Nikon to release the dev kit.
UPDATED: Erica Barker reached out to us, stating that her original video has some information in the tutorial that was inaccurate, and unfair to Nikon. We have changed the video out with the updated one. Thank you to all our readers who informed her of the inaccuracies.
