That's the problem, Sebastian: all the files I used, be it in RAW or converted in *.TIF, had the EXIF datas intacts !
I just loaded a set of 3 RAW (*.NEF) images in SNS-HDR and made an HDR file, then loaded the same 3 images, BUT CONVERTED in *.TIF, in SNS-HRD and created another HDR file !
Next I loaded the first HRD image (created from the RAW files) in PTGui and it didn't recognized the focal length:

Later I loaded the second HDR image (created from the converted *.TIF) in PTGui, and it accepted it without problem !
Strange, isn't it ?
