I just bought the A7Sii. In the Library module view of the Metadata, the correct model camera and lens models are automatically appearing correctly. In the develop module however, in Lens Correction panel, the Make comes up "None". If I change that to Sony, it automatically takes one profile, a completely different model lens and applies it. If I try to manually select the correct model lens, it only has the one incorrect lens model available. These are only current model Sony and Zeiss lenses that I have and I'm not using any third party lens adapter.
Are you shooting raw images? Lens profiles are file format-specific.
