When I "enable lens correction" in Lr, I get the "can't find the lens message." I have a new Fujifilm X-T2 and multiple Fujinon lenses. There are no Fuji lenses in the list, so I can't enter that. Am I out of luck?
Make certain you are viewing a raw file and not a JPEG. Most lens profiles do not exist for JPEG files.
Does the bottom of the lens panel not show "Built in lens profile applied" ?
As far as I am aware Fujifilm mirrorless cameras like other models from Olympus, Panasonic etc have builtin lens correction info in the file header of the raw files from the camera and these are automatically applied by Lightroom /ACR it is not something that can be turned on/off.
This as designed by the Camera Manufacturer.
See the screen capture which shows and info note "Builtin lens profile applied."
