My camera is Sony A7C2. I have a Sigma 60-600mm F4.5-6.3 DG DN OS (S023) lens but Photolab 8 (version 8.5.0) cannot detect this lens correctly (it will be detected as wrong lens Sigma 60-600mm F4.5-6.3 DG OS HSM S, which is not possible for Sony camera since it is never available on Sony mount).
I also tried to manual download the module but I cannot see this lens after I selected A7C2. Does that mean we cannot get this lens supported on A7C2? Or, is it a bug or something?
Report this to DxO via their official support channel. I expect they would ask for an example file so they can inspect the EXIF data.
