#77 Vignetting lines added to wrong lens

[COMPUTERFREAKED]

Refer to https://sourceforge.net/p/lensfun/features/67/

I cloned into the latest version in github. There are 2 versions of this lens in the database:

30mm f/1.4 DC DN

and

30mm f/1.4 DC DN | C 016

The vignetting lines I sent in the above mentioned post were added to a different version of the Sigma 30mm 1.4. Mine were shot with the A6000 which identified itself as 30mm f/1.4 DC DN | C 016.

Darktable confirms this since it matches my lens to the 30mm f/1.4 DC DN | C 016 hence vignetting corrections are not available.

I wonder whether there are truely two different versions of this lens, or whether both entries should be merged …

Do the TCA/distortion corrections of the current “30mm f/1.4 DC DN | C 016” work for your pictures?

[COMPUTERFREAKED]

Yes they do. I have now manually cut the vignetting lines from the 30mm f/1.4 DC DN to the
30mm f/1.4 DC DN | C 016 and all works well.

To be clear: I provided the vignetting lines for this lens. Mine identifies as 30mm f/1.4 DC DN | C 016. Hence the vignetting lines I provided were added to a different entry for the sigma 30mm dc dn.

As far as I know there is only 1 version of this lens but thats just me...

I merged the two entries, and the new one matches the C 016 part as well.
