P: Rings/Vignetting with Tamron 17-70 Lens on Fuji XT-4

Definitely! I really need to get around to picking up a Fringer to use some Canon or Nikon lenses. Some of those Sigma 1.8 Art lenses are really nice. 

> However, since the Fujifilm system lacks choices in terms of fast aperture zooms (only two other options, neither of the others with lens stabilization)

it only lacks in native mount... consider adapters and you have tons of "fast" AF zoom lenses to use, some will be even wider than that dark 2.8 aperture 🙂

Checking back in on this again as well. I do all of my work in Adobe CS (especially Lightroom) despite owning other processing and editng programs for testing and tutorial purposes. I really would like this lens to be functional for use in Lightroom the way it is on those other programs. 

I know that Fujifilm's overall is relatively small and it might make a bug like this a bit lower priority (5% overall market camera market share, and that's including Fuji's Instax products).  However, since the Fujifilm system lacks choices in terms of fast aperture zooms (only two other options, neither of the others with lens stabilization), the Tamron lens is a *really* important lens for the overall system. Fixing this bug - what I assume is a lens correction profile issue - would be a big help to Fuji users on the Apple M1 platform.

Yeah, unfortunately it's still a problem. I also encountered less of a problem stopped down, but like you said, this isn't the solution to the bug.

Any Updates about whether or not this can be adressed in a firmware update?

Adobe knows this, but will it correct it?

Took the lens out for another shoot today. Yesterday I used my X-T3, today I took out my X-H1. Similar to the other two posters here, the lens correction in Lightroom puts double vignette concentric rings on the RAF images when the lens is shot wide open at f2.8.  The effect seems weaker at f4 and all but gone by f5.6.  Still, "shoot at f5.6 and up" is not really a viable shooting strategy. 

I am running into this issue with the Tamron 17-70 + Lightroom Classic & MacOS as well.  Has there been any progress on this bug?  It is not appearing when I process the same files in Capture One 22 or in Affinity Photo. 

Hello Adobe, is there any news about the solution to this problem? In the latest versions of Adobe the double exposure ring still exists.
I am waiting for a solution.

In the new version of Lightroom 12, they have not fixed the problem. The exposure rings still appear.

I was shocked when he didn't see the show rings. He deleted my messages and didn't reply to the last one. It seems that he does not accept criticism. He is the same person who discarded the Fujifilm 16-80 because it "breathes" and the focus changes when he zooms. I'm glad Adobe responds to this issue and look forward to the LR update.
