Good point, Mike. I tried all three settings: Auto, Custom, Default, but without success.
For the life of me, I can't get LR to recognize the X-Pro1. It seems that LR doesn't recognize the camera in develop module - it does whoever, properly note camera and lens in the metadata. So I understand that LR is simply ignorant of any X-Pro1 profiles.
Early December I had the problem that LR recognized my X100T files as shot with either a 19mm or 33mm lens. (metadata and in develop module) But the camera has a 23mm fixed lens. Optional lens converters are available to create those two alternative focal lengths, but I don't own them. I had to perform a factory reset of the camera to get things back on track. Computers! Strange things happen every now and then.
