Nikon has posted a Distortion Control Data Firmware Update. Distortion control data are used to correct barrel and pincushion distortion during shooting and editing. They can be loaded into cameras that support distortion control. The D800/800e are two of the DSLRs which support DC.
You need a fresh battery to update firmware. As Ned found, this update is very fast.
The firmware update is the same for the D7000. My update of that firmware was also very smooth. I used the same SD card to update both cameras without reformatting when I moved the card from one camera to the other.
Do you know if it is possible to "fool" the D800 so it believes a non-Nikon lens is a Nikon lens and automatically applies distortion correction either we want it or not? For example,when I read in Capture NX2 the metadata of photos taken with my Samyang 14mm f/2.8, it says Lens = 14mm f/2.8-1.4D !
We know that if it is turned On, it is applied to JPEGs. Is it "baked into the RAW file" as the file is generated, and therefore applied to all images regardless of the RAW converter?
Some Raw converters have other distortion control mechanisms. I assume with those products you would keep the Auto Distortion Control turned Off, and use your software for distortion control. If you left it turned on, then there is a question of whether the third party product would recognized correction had already been applied.
This Distortion Control is different than the Distortion Control available in Capture NX2. The Capture NX2 Distortion Correction is for images from wide lenses. It corrects a slight fisheye effect at the default setting of 10. At the extremes of +100 or -100 it either over corrects or creates a strong fisheye effect. The Capture NX2 correction does not consider the lens being used - the effect is the same on images from a 24-70 and a 70-200.

It's not baked in to the raw file, and other converters don't use it. It's benign to keep it "on" if you're using other raw converters, and if you choose to shoot in raw + jpeg mode it can be a benefit. For example, I have the distortion correction enabled in the camera and the equivalent (but different) function enabled in LR4/ACR7. That works fine with no conflicts or problems. If I was processing jpegs in LR4, I'd either want the distortion correction in LR4 turned off or the in-camera correction turned off, but with raw files, it's no problem. Other programs such as DxO will likewise ignore the in-camera correction in favor of its own and most others use manual forms of correction and can't see the in-camera setting.
I am at least a bit confused. Why would Nikon put distortion control in both their cameras and in their PP software NX2. NX2 does not ignore NEF file setting, so one would think something might be going on in camera that is burned into the RAW file.
The in-camera setting alters jpegs, as well as the jpeg preview for raw files. The fact that it's set to "on" is simply a tag. If you want to prove it to yourself, try turning on and off distortion control in NX2. If it were baked into the file, you wouldn't be able to do that. In addition, just open up NEFs in another program and compare the results. Without distortion correction enabled in that other program, you'll get different results.
Why would Nikon allow you to turn it off in NX2? Sometimes correcting distortion isn't always the right thing for an image, and there's a small reduction in sharpness.

I'm exploring Canada until mid-July, with no access to my files at home, but when I get home I'll post an example of a picture where the profile (distorion) correction of LR4 clearly reduces sharpness.
I shoot raw+jpeg fine with the cam auto distortion control setting turned on. I am currently trying to determine if the cam burst speed is significantly affected when using this setting. So far, using sandisk extreme pro 95mb/s cards I can't detect a difference in burst speed and buffering between either the on or off settings. So I plan to keep using this latest L1.009 update with cam created jpegs. By the way, as noted in multiple threads across the forum, this latest distortion control update is now available via link from the new nikonusa support site. The list of nikon lenses that are supported by this update is extensive, and I have no reason to believe that only the newest nikon lenses will benefit from this update. good luck
Historically, while specific country and regional Nikon websites have had links to the distortion control data firmware, the actual files have always been on the "nikonimglib.com" server/site, as they continue to be.
It turns out that all firmware updates are actually hosted on that same server/site which can be seen once you begin downloading the actual firmware files themselves.
It does make sense from a management viewpoint that there is only one server/site to upload the files for distribution, and then have links on the Nikon regional/country sites to the repository. It makes it easier to ensure the latest updates are the ones available, and are available to all Nikon users.
The Nikon USA site does have an easy to find link to the update.
