I had a look on this page: http://lensfun.sourceforge.net/manual/addcamera.html and followed the instructions. d = sqrt(23.6^2 x 15.6^2) mm = 28,29 mm cropfactor = 43.27 / d = 1.5295 usage of exiv2 and a *.RAF image: Camera make: FUJIFILM Camera model: X-E3 So the XML entry should look like this: <camera> <maker>Fujifilm</maker> <model>X-E3</model> <mount>Fujifilm X</mount> <cropfactor>1.53</cropfactor> </camera>
Support for Fujifilm X-E3
