Google Translation: "I have a Sigma 50-100mm Art. Tried with Lightroom Classic and Lr, both can't find metadata. Yet in the photo info, they got there. I can't do distortion correction etc. "
That lens' full name is "50-100mm F1.8 DC HSM | Art", and it's a lens supported by Adobe. Troubleshooting steps:
1. In Develop, type "i" until you see the file name -- are you editing a raw or a JPEG? Most lens profiles only work with raws. Many people here have unintentionally edited a JPEG, thinking they work working on a raw. So don't assume -- verify by typing "i".
2. If you are editing a raw, upload a sample raw taken with the lens to Dropbox, Google Drive, or similar and post the sharing link here. That will make troubleshooting more efficient.
