Hi,
since I wasn't satiesfied with the result of lensfun's distortation
correction (at short focus lengthes),
I approached it the problem a different way. To sum up the results are
optimal - in a certain sense, see below.
This is what I did:
- prepare a sheet of paper with some labeled grid

Thank you very much for your work and for making it available!
I included your TCA and vignetting data, leaving the old distortion
data for the time being. It has the advantage of covering focal

It should work again.

We have distortion data for this lens for a couple of weeks

A big thank you also from me!
One question, though: The distortion figures are rather small.
Maybe the designation as a "fisheye" lens is missing? Could you

You mean that vignetting and/or TCA correction data is missing?
