Would like to better understand D800 and Df Distortion Control, especially the Auto mode of operation for Nikon D-AF and G-type lenses (which obviously have a lens CPU). Is there a definitive lists of which Nikkors are supported? Is the correction applied the same for both JPEG and NEF files? Is the NEF file altered in-camera, such that it is permanent, or is it a parameter embedded in the NEF file? Nikon View NX2 does indicate Auto Distortion in the EXIF data, but does not allow you to select or unselect it in the presented image, or control it prior to converting to JPEG, for example. How effective is it for complex distortion, such as the wide end of consumer zooms? Do you use in-camera distortion correction or do you apply it is post? If applied in post, what post-procession software do you like?
