http://rottmerhusen.com/objektives/lensid/nikkor.htMmmm, it sounds like Nikon people will have plenty of problems using
non electronic lenses.
This highlights the fact that many of us use lenses that are not
recorded in the exif data. Hence it is necessary to have a way to
manually specify it.
With respect to shift from center (d,e), I don't think it is
critical. Most people will be happy with an approximation. Remember,
this is to correct one photo only.
Also, it would be nice to be able to specify the output projection
too. For instance, I frequently remap fisheye (equidistant) to
stereographic.
