Thats interesting, Lars, because I had this before with both my ZE 21 and ZE 35: they show up in Lightroom as 21mm and 35mm, but just for a few hundred shots a year ago or so. Later (and previous?) shots show up like they should. That can't be due to a camera change or so, I haven't find out how this happened or with what possible change in the workflow it covaries.
