means that proper correction would have to take focus distance into account?

I'm not suggesting Lensfun be expanded to take focus distance into account, my
impression is that this aspect of EXIF data isn't very reliable (yet) anyway...
I was only suggesting that this could explain why a trustworthy TCA dataset
could still produce the (non)correction the original poster

I'm sorry, I think I was just aware of Hugin no longer including Lensfun
support, and just incorrectly assumed it was due to correction
AFAIK, using the current git db should be fine for 0.3.2, but probably not
earlier versions without some modification.

Yes, the lens correction profile for a given lens can be used for any sensor
size which is the same (as in this case) or smaller (by adjusting for crop
factor) compared to the one used to generate the profile. You may need to add
an "adapter" within lensfun to tell it to allow lenses with one
The files in that tarball seem to have been last updated almost two months ago;
I don't know what determines the schedule for that. The bleeding edge database
is available at the git repository:

but there are a couple of caveats. The
Hi, thanks for the profile. I checked it against a batch of images from a
review taken at different distances, and it seemed to slightly over-correct at
the furthest end of the range, so I made a slight adjustment. The attached copy
is what I plan to add to the database, unless you find that
