Tamron 17-70mm 2.8 Ring/Vignette issue in Lightroom (w/ Fuji XT-4)

[Ruben_Kempter]

Hey there,

I hope you can help me with this, it's driving me insane.

I noticed the problem first when shooting into a blue sky with clouds at a wedding, then I saw the problem on a table the next shoot as well. Now I checked with a white wall and found that Lightroom actually does this to my newly picked up Tamron 17-70 2.8 (on a Fuji XT-4)

I'm having crazy rings and vignetting with the Tamron lens, first thought it's the lens, but it's Lightroom adding the crazy rings. Since when I'm importing there's nothing, but when i hover over the image and select it, it takes a second and then Lightroom adds them to the picture, as if it where implementing a lens correction, but horribly wrong. Turning off Lens Profile / Correction doesn't do anything, once it's there it's there. Also the JPEG looks fine, it's only the raw file.

Here are the images

Here is the RAF File, maybe it's just me: https://www.dropbox.com/s/ujq73k71qxl01a7/_AAA3049.RAF?dl=0

Can you please tell me how to fix this, and what is going on there?

PS: Fuji XT-4 and Lightroom are both updated to their lates version/firmware

I am in contact with Tamron Germany and they're in contact with Japan and I have gotten some responses on the Adobe Forum.

What we've got so far:

- It is probably a bug with the combination of a Mac and Adobe (Camera Raw, LR, PS etc.)

- In Capture One and other programs the problem is not that serious almost not there at all.

- And Tamron said that they tried on a Windows PC with Lightroom and also had NO problem.

But since it's not my copy of the lens rather than the combo of Mac + Lightroom + Those RAW Files seems to be the issue I wonder that none of the reviewers, and almost no one else on the internet seems to have that problem, I cannot imagine I'm the only one using that set up...

Yes that looks pretty bad. It does sound like it's a bug/problem with the lens profile on your particular setup. However, you say that when you turn off lens corrections the problem remains? That sounds inconsistent with the above, unless Adobe are applying automatic corrections which can't be turned off (which they do with some cameras but not usually ILCs). It sounds a bit like it's getting double-profiled - maybe the adobe one being applied on top of an embedded one? Is it possible the camera is embedding false profile info in the file? Have you tried turning off lens corrections in the camera?

Have you updated to the most recent version of Lightroom/Camera Raw? Guessing you have, but if not you should do that because they sometimes update profiles.

Another thing to try would be to create your own profile - think you can still do that with Adobe Lens Profile Creator, or search to see if anyone else has done it for your camera/lens and made it available.

Incidentally but interestingly, there is actually some circular banding visible in the jpeg image you posted. Nowhere near as obvious but still there.

I am experiencing the exact issue with the same hardware/software combination. And I am also supprised I could almost found no one saying anything regarding.

Apart from ring/vignette, when I compare the in-body generated jpg and the raw, there might also be some kind of geometric distortion goes along with the rings! I haven't yet shoot at a chart reference or sth to judge which is distorted, jpg or raw, or both, in different ways. But there must be something wrong here.

The problem seems to only occur with the X-T4 camera, Tamron 17-70 lens, and Adobe software. With the X-H2s camera (for example) the problem does not occur.

Is it also produced with the X-S20, which has the same sensor as the X-T4?

Could someone with the X-S20 check if it occurs?

Adobe has recorded the issue, but has not fixed it yet.

Hello. This issue has been fixed by version 15.5 of Adobe Camera Raw
