Could you send me the presets? I can try them in my version of Lightroom and let you know if the same thing happens.
Thanks! I can't seem to get them to show up after importing. Do you think there are different profiles for the GRIII and GRIII X?
It looks like it was locked to the camera name, I manually changed them to RICOH GR IIIx and they appeared. Although they do look slightly different to the jpgs from the camera. I've attached them here incase anyone wants to try them with a GR IIIx.
