Photoscan cannot retrieve focal length from FLIR Duo Pro R visible camera EXIF

[3DWinter]

Hello Agisoft team,
this is the first time in year on working with camera imagery I came across a peculiar situation. It seems various OS (Windows, Linux) and so as Photoscan cannot retrieve the focal length from the EXIF header.  Digging in with Python and Exiftools, I can confirm that the focal length is indeed there, it is 8mm and it is the same number for both EXIF:LFocalLength and Compositefocallength35mm- which obviously one of them is wrong.

Please advise me if I am doing something wrong, is it is a corrupted image.
thanks

Hello 3DWinter,

It seems that these tags are in the main IFD instead of EXIF IFD, so they are ignored, since are not found in the proper location.
