Andrew,
Mathematica supports raw bitmaps (of which .nef might be a type) but
it does not explicitly state .nef as an excepted format. The way to
check is to run
test = Import["image.NEF", "RawBitmap"]
You might need to specify the size with the option  ImageSize ->
{2000, 3008}

If that doesn't work you probably need to convert it into a more
standard format such as a good quality JPEG, the software with the
camera should be able to do this.

Hope this help,
Phil
