Is there a lensprofile of the fujifilm 16mm f2.8 for Darktable already available?
Check the lensfun database on https://lensfun.github.io/
if it is not supported, create a correction profile yourself:
I do not have the lens yet. Was just curious a correction profile was already made.
Yes, it has been made, although I update regularly lensfun (from terminal with
lensfun-update-data). So if it does not come with your distro default package, just run the “terminal” update.
I only see the profile for the 16mm f1.4. I mean the new fujifilm 16mm f2.8 R WR lens.
Hi @RMA, I already have the vignetting and distortion calibration for
the new XF 16mm (https://github.com/t3mujin/lensfun/blob/master/data/db/mil-fujifilm.xml), but haven’t did the pull request into lensfun project yet because I still haven’t done the TCA correction.
Often you can just use the distortion pictures for it. Did you try it to generate them and check if it works?
I just corrected the title. Put for instead of dor and darktable instead of Darktable. Hope it’s okay.
The new 16mm f2.8 is in delivery for comming weekend. So i hope to see a lensfun update soon. Many many thanks upfront:+1:
You are right, I miss-checked the thing, you are right
Actually I didn’t, but since my distortion images weren’t “contrasty” at all I didn’t even tried. I’d rather have good samples. It’s just a matter of getting a good sample and running the scripts, but I haven’t been able to that simple thing for the last couple of weeks
Yesterday I received the lens. I can send you some RAF files. I do not know how to use a script. In Darktable the 16mm f2.8 is recognised as the wide end of the 16mm to 55mm zoom😊
Let me know what you mean with contrasty photo. Greetings.
Thanks, but there’s no need, I’ve had the lens since it came out and right now I may even already have some good enough samples in my archive :D, so I’ll take care of that soon and run the script to submit the pull request. But even after me doing that it may take a bit before a new version gets released, so meanwhile you can replace the mil-fujifilm.xml in file in your lensfun installation with the one with my changes (https://github.com/t3mujin/lensfun/blob/master/data/db/mil-fujifilm.xml), it already includes the distortion and vignetting corrections for the 16mm f2.8. My updated file has been the one I’ve been using in darktable for the last weeks.
Many thanks for your reaction. So I do have to replace the xml file. Lensfun on my Manjaro linux systeem sits in usr/share/lensfun. So i have to replace there the xml.file and restart?
Do i have to have a account to get the xml file from Github. I don’t see any download link after activating your link.
Hope to hear from you.
Did found the directory of lensfun-updates on my system. Was in /VAR/LIB …
I did change the xml file with your extra code.
Now it functions.
Darktable detects the 16mm f2.8 r wr lens.
Big barrel distortion compensation when taken a object short to the lens.
Sorry, but I’ve away from the computer in the last couple of days. Glad you found your way to change the database
