How did you check that? It might well be, that there's just a flag in the file, which RAW converters interpret, but the RAW data itself is untouched.

Good point and you are right!
As you can see I first wrote "it does not show any effect in RAW" because I was sure it did not.
But then I have used the new ViewNX 2 to view the RAW files and auto-distortion control DID have an effect.
I can't verify it right now, but I think ViewNX 1 did not correct distortion. (will test later)
Now I checked with rawtherapee and auto-distortion control shows NO effect.
So it seems Nikon places the distortion control parameters in the NEF and their own RAW converters are able to interpret them. Or ViewNX 2 recognizes the lens and does a distortion control on it's own. But I doubt that.
