Thank you. I may try that. But I don't really understand why it should
be that hard. Presumably, the program darktable and the gimp filter
gimplensfun are looking somewhere to find correction information. If it
is not in /usr/share/lensfun, where in the world is it?

I ordinarily work in darktable on NEF fiiles, but I somehow managed to
nuke a whole bunch of NEF images and had to instead work with the jpeg
images on my backup card.

It is perhaps an exaggeration to call these "the" standard lenses for
the d800. When I was contemplating laying out a fortune for my D800, I
posted a query at Nikonians about which lenses I should consider given
my needs. The 24-70 and 70-200 lenses were both strongly recommended by
several people. Also, my Calumet salesman recommended those same
lenses. I think these lenses are common choices for use with the D800.
They should definitely be in the Lensfun database, and if my reference
above makes any sense, they are, so I am perplexed about why I can't
Fortunately, my lenses have very little distortions, so I may be able to
avoid using corrections.
The 14-24 lens was also recommended, but I didn't think I needed it, and
I had already spent enough money. Later I got a 24 mm tilt-shift
Rokinon lens which was something of a bargain for under $1,000.
Perhaps I should explain that I have been doing view camera 4 x 5
photography with 75 mm, 90 mm, 150 mm and 300 mm lenses. I wanted the
Nikon D800 to cover roughly that range. 24 mm is relatively short for
35 mm but not as short as 75 mm is for 4 x 5, so someday I may get a
shorter lens for my D800. One of my interests is architectural
photography, and my 75 mm lens wasn't even short enough to photograph a
building facade from across the street. I had to stitch two images
using hugin to capture that scene. I think I can do the same thing
easily, if the need arises, using 24 mm on my D800,
If I feel a pressing need, I may get a shorter focal length lens for the
D800, but given that I am 80 years old, that need may never arise.
