Strange Tamron 17-70mm vignetting

Neither Fujifilm's software, nor Capture One, nor Darkrable, nor Affinity Photo give the double vignetting problem.

But have you tried them with the built-in Manufacturer's profile? Lightroom uses it by default, but other software does not.

Also, I've got a few RAWs on my computer from other Tamron 17-70s with no vignetting issues at all in Lightroom.

How do I apply the manufacturer profile in LR? The vignetting does not appear in all my photographs either and when it appears it is a few moments after importing it into LR. The photo looks good and LR does something and vignetting appears. Thanks for your help.

Lightroom applies the built-in lens corrections automatically at import - and (unfortunately) it can’t be turned off.

That seems not to be completely correct in this situation (Tamron on Fuji). If you look at Baobab’s screenshot you see something you do not see with Fuji on Fuji. I'll try to show screenshots later, also comparing to my own lens, which does not show this.

You are right below are the good ones :

In ACR PS you can turn it off

What I see looks more to Newton's rings due to luminous interefrence by reflexion rather than some vignette artefact

Newton rings can appear either by transmission or by reflection.

To support even more that hypothesis, the fact that it disappears after f 4 which is in favor of some reflection

remains the fact that only Adobe ACR engine sees it and when I use my own gear I have no issue.

Any idea of possible unwanted reflection ?

This video clearly shows the error. I wrote two comments on the video and he deleted them and the third comment he never answered me.

Starting at the 5:20 mark, very obvious to see. I use the lens on my X-T3, but I don't use Lightroom, and I'm content to shoot mostly jpeg, so I haven't noticed this behaviour.

Hello!
Any updates on this issue?
I wonder why Tamron doesn't address this to Adobe? They (Tamron) may lose a lot of sales because of it.

No. Neither Adobe nor Tamron have released any updates that fix the issue. From Tamron Spain they insist that it is an Adobe problem, because with other editing software the error does not occur and Adobe does not respond. It's a shame because the Tamron 17-70mm f2.8 seems to me the best standard zoom for Fujifilm X.

thing is the problem is not on all lenses. I downloaded one of your files. In FastRawViewer which does not apply corrections the image was 'clean', in Lr it was bad. But images from my own lens are OK.

I wonder whether there was some unacknowledged change in the lens? Mine was bought first week of January

Same here never had the issue, I work with PS and ACR for raw

When did you get yours?

baobob · Mar 10, 2023

I have retried your RAF files at f 2.8. With IXT set to ignore profile everything is ok with my PS ACR last version. With profile it reveals this circular pattern.

I tried with my XH2 and XH2s to reproduce the phenomenon bu all results are ok just showing vignette easily corrected.

So I cannot say that my lens could be wrong nor that ACR in PS could do something wrong.

Looking at cameras owned by posters lead me that your XT4 couldbe the source of the phenomenon : what I see again looks like Newton rings created probably by some relection astrong hypothesis since it disappears from f4.

The fact that only Adobe raw developper reveals it with the lens correction IMO onlmy means that it is hyper sensitive to a probably mild reflection. The fact that if I understand right no posters were able to reprocuce it IMO seems to lead that the issue is located to either the lens or the camera but not in the softaware itself.

from one of Fernando's files [hope this is ok with you]

FastRawViewer: no corrections but vignetting

LightRoom: the problem. With built in profile [which cannot be disabled

I cannot copy this with my lens

The third one is weird and maybe useless:

Lr with Tamron profile, probably for another mount

Note that correction of the vignetting seems to be applied twice, and the problem is there

Thayt does not accounts for the rings nor for the fact that it disappears from f4 and higher ....

Someone needs to process this RAW in Capture One using the Manufacturer’s correction profile option, not Capture One’s own profile to see if the problem still exists.

Oddly, this should be reported to Adobe due to the strange way Adobe works with manufactures.
