Hi,
If I use the lens correction and I ask for "vignetting only", I get also
some kind distorsion correction, or at least I can see the image is
resized/cropped. This is not exactly the same as when I ask for distorsion
correction.
In fact, I soon as I select the module, even if distorsions are
Hello, I tried to save a style on which the "perspective correction" and

they were already set. Is there a way to pre-define or to be able to
activate t

You are right, things

Thanks for the details Simon.
I also thought about it a bit and had a reasoning similar to yours, that
basically something designed for a specific acquisition chain will probably
perform worse on an acquisition chain farther from its spec.
However thinking about it more deeply, 2 things are still
In the database (in liblensfun-data package, file slr-canon.xml for Canon),

Hi,
it does, as long as lensfun can find the lens in its database. I've been
using full-frame-only lenses on both my Nikon D750 (full-frame) and
D7100 (APS-C) for years.
(It's not the best idea, though, so I'm about to replace the D7100 with
a second full-frame body).
cheers,

I believe it does. Changing body type (full-frame instead of aps-c)
changes geometry. Body type description is nothing more than just a
file in /usr/share/lensfun/version_1 with cropfactor parameter being
the only meaningful information used for geometry calculaton.

Hi,
I happen to use on my Canon 750D (APC-C) 2 lenses designed for full frame
(Canon EF 50mm f/1.8 STM and Canon EF 28mm f/2.8 IS USM)
I wondered if the lens correction module takes into account that the camera
is full frame or APS-C to apply the proper correction ?
Can someone tell me ?
Thanks

Tested your solution but still does not work.
Seems the only possibility is to downgrade lensfun from 0.3.2 to 0.3.1
I already opened a bug issue with Leap developers that already asked for
more information.

Hello,
just upgraded darktable and recognized a problem with my setup: lens
correction module does not show the camera as well as it reports to
choose camera and lens manually.
Trying to choose the camera and lens does not show anything, just an
empty chooser, no camera or lens to choose.

On the plus side, distortion is not, and CA is relatively easy to correct.
Vignetting is hard to manually correct with the current darktable modules,
