The Tamron 17-70mm lens with the X-T4 produces a strange double vignetting, which is most noticeable when photographing the sky. It appears at aperture f2.8 and is most noticeable at 17mm focal length. The effect disappears when the aperture is set to f4 or higher.
I hope Tamron service will fix it or replace it with another lens.
I leave some examples in jpg.

Do you have a polarizer or any other filter on there?

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?

That was my first thought and then I noticed there is more than one ring. Possibly a lens profile issue though I've never seen one do that.

Or maybe the sun switched to LEDs.

That's it! The sun is trying to save energy as it's hydrogen bill is getting out of hand.

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.

Interesting, I'll try it with mine this week on my X-T3 and X-S10. I normally just shoot and edit jpeg (🤫) but I'll try some shots like this in raw to see if I get the same effect.

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).

Has anyone taken test shots with the Tamron 17-70mm f2.8 for Fuii and processed them with Adobe software?

Here's my vignetting calibration shot at 17mm/2.8, if you want to see if both my lens and yours have the same problem:

https://drive.google.com/file/d/1-ytthPwITTtUKO2iwvSCz_raUOvocfJu/

If Adobe software is reading the correction profile directly from EXIF, then either it's reading it wrong, or the lens is giving the wrong data.

Here's the SOOC Preview extracted from the RAF's EXIF, both distortion and vignetting looks good, so at least the lens relayed the correct profile to the camera (thus, unlikely to write the wrong info to EXIF?).

darktable/lensfun doesn't have correction profile for this lens yet, so I had to calibrate one myself:

https://www.dpreview.com/forums/thread/4665938

Here's your shot without and with distortion+vignetting correction in darktable (using my own calibration):

from darktable, with no lens correction
from darktable, with no lens correction

from darktable, with distortion + vignetting correction
from darktable, with distortion + vignetting correction

My distortion correction is still slightly off in the middle comparing to SOOC. I'll have to calibrate again soon. Better yet, I should adapt the new script to extract the correction data directly from the EXIF:

No one else has this problem?

No one has this vignetting when importing/editing RAW files with Adobe software?
 
Although Adobe has been made aware, in the Adobe community forum, of the double vignetting error of the Tamron 17-70mm f2.8 lens for Fuji, nothing has changed in the latest version of LR, ACR or PS.

If you are thinking of buying this lens and you edit with Adobe software, I give you a recommendation: WAIT, the bug is still there.
 
My lens does not do this.

We pretty much determined this to be a lens firmware/profile issue. I don’t think it’s Adobe that needs to come up with a fix. I would try complaining to Tamron to sort this out.
