FoV. You can see the results at http://www.lemis.com/grog/photos/Photos.php?dirdate=20201002. The not-so-good news: the fast panorama preview makes a mess of the display, and may be the reason that you thought it didn't work. But the normal preview (the one nobody uses) shows the display c

Maybe discrepancies in lensfun? Not all the same version, not all updated? Run lensfun-update-data. Hugin only can benefit from good lens parameters if they can be found in the database. http://lensfun.sourceforge.net/usage/ Luís Henrique Em sex., 2 de out. de 2020 às 07:38, giuseppe por

Hi, Sorry, I made some mistakes and bad assumptions. I tried with these lens parameters: fisheye full frame; focal length 2,8; crop factor 5,6. It stitches. From the exif data it seems you use a gopro 6 black. I took sensor and lens data from specs of this gopro version. Hope that may help. Regards

Hi, I gave it a try. In my case Hugin does not ask for lens parameters because the exif data give rectilinear: 98 degrees Hfov, which seems the case considering the relatively low distortion. In the five equatorial pictures CP detects enough control points. It does not in the zenith and nadir pictu
