Hi! We have Zenmuse XT 640 30hz Advanced Radiometry with 13mm lens but I found that camera writes to exif focal lenght 9mm instead 13mm. Have anybody same problem ? Question for DJI support: how to fix this ?

Mine has the same problem.   I was attempting to do some mapping and noticed this as well.   I have contacted the FLIR dealer and they acknowledged the problem and have already spoken to flir about it.   I spoke with them yesterday.

I've got the same problem with a M600 Zenmuse XT (640x512, 30Hz, radiometric, 13mm).

I also have a problem with the GPS longitude being populated in EXIF. It is consistently incorrect by about 1km to the east.

ETA, which software are you using to create a mosaic of multiple thermal images?

What's your experience with the isotherm settings? What settings are you using for NADIR mapping?

Thanks,
Eric
