Is it some lens profile that is not correct? If you capture a RAW and view it in a tool that does not enforces the lens profile (e.g. capture one, darktable etc), does it look the same?

The effect appears in the raw files, only with that lens. I have tried with other lenses and the elect does not appear. I have some raw files uploaded here: https://www.dropbox.com/scl/fo/dkd7rm2pa5mm5thtdadiv/h?dl=0&rlkey=aadkrrd72jaoxuyi5s2cekmkz

You are experiencing a profile issue. I opened one the RAW files in Photoshop and it looked the same. The JPEG you posted was processed in Elements, also an Adobe product. I then opened the file with a different RAW viewer and the concentric rings are gone yet the corners are dark.

What solution do you propose?

Definitely faulty firmware in the lens. See if there's an update.

I did a quickie edit with one of your RAWs with some manually applied corrections in Lightroom after first stripping the metadata correction data with Iridient X-Transformer...

Thank you !!! I can't find any firmware for this lens on the internet. I think I'll send it to Tamron technical support.

Yeah, send it back. There are certainly are people using that lens without problems so they ought to be able to sort it out. Has anyone tried this with Capture One? It can switch from the manufacturer's profile to C1's own profile, or to no profile (I think).
