I contacted support by chat regarding Sigma's new 85mm dg dn art lens. There is no lens correction profile yet, and they have no idea when one will be released. They sent me a link to a lens profile builder, which is no longer supported. Looks like it hasn't been supported for some time. I'm trying to manually correct for this lens, but wanted to know what correction settings you all are using so that I can compare it to mine. Hopefully, Adobe will get on this quickly.

The Adobe Lens Profile Creator is still supported and available for download:
https://helpx.adobe.com/photoshop/digital-negative.html#Adobe_Lens_Profile_Creator
The Downloader that provided a space for sharing user-created lens profile is no longer supported, but that's not needed to create your own profiles (and share them via other means with other users).
Add your request for an Adobe lens profile to this thread in the official feedback forum, where Adobe wants all such lens requests:
They're typically not very fast in profiling new lenses (and they may or may not get to it for this lens).

I've tried installing the Lens Profile Creator for Mac, but I get this message, "The developer of this app needs to update it to work with this version of macOS. Contact the developer for more information." I have the newest version of Mac iOs. I'll submit my request. I have been able to somewhat manually configure a lens correction for the time being. -DW

You are right. I just tried and it won't run on Catalina. Probably because it is not a 64 bit app. It's been over a year since I used it so I hadn't noticed this. Clearly we don't have an option anymore now.

It appears that the app needs to updated, I also got the message when I downloaded the app a couple hours ago. The install on macOS 10.15.7 failed.
On another note I am surprised that you would find a prime lens with the specs 85 mm f1.4 would require a lens correction profile? I took a look at the sample gallery at DpReview and do not see any obvious problems.

It probably has significant vignetting at f/1.4. I would imagine basically no real distortion.

It actually has major pinchushing distortion, visible big time when you shoot a brick wall. It is a new release from sigma, and the pincushing undoutably was created when they made this lens specifically for mirrorless. It's much sharper than the 85mm GM from Sony, and a bit smaller, but with pincushing... 😞

It is pretty easy to create a correction profile with the lens profile creator app that John links to. I've done these for a bunch of obscure lenses that I own. Very simple and pretty quick. All you need is to print out a chart on a large sheet and mount it on a flat surface and then take pictures of it in homogeneous lighting. The app figures it all out as long as you are able to photograph the chart in a way that the images overlap and that you cover the entire lens. The instructions are very clear and easy to follow.

Sigh. I keep virtual machines for Mac OS 10.14 and Windows for such issues. You might post a request on that same feedback forum. Above has built 64-bit versions of other tools on request.

any resolution on this issue? i'd love to get a profile for this lens.
the best i've found so far is from dustinabbott.net's review
quoting his correction here:
I found that it took a -11 on the distortion slider and a full +100 and midpoint to 0 (max correction) on the vignette sliders.

Absolutely no resolution at all. Doing some myself, I found that a -9 on the distortion slider and vignette of +22 and midpoint at 0 works very well. I think +100 is way too much, looking at his example, the edges are exposed way more than the center.

Let me also add that the adobe profile creator for Mac is still not updated to work with the current ios. I have to manually enter the values for each photo.

what a shame. hopefully this lens is added soon. do you know if there is somewhere we can submit feedback to adobe directly requesting this?

I did a fashion shoot with repeated vertical and horizontal lines in a tunnel. I get around -9 ish for distortion. This lens is so much sharper than the GM 85 and the focus is faster. The image (color and contrast and refocused areas) are as good or better.... but I agree the pincushion is really really strong. Like bad - much more than any lens I've ever used. If I take a photo of an object on the edge of a table (like for eConmerce) it is really bad - unsuable as is; but easy to correct with the slider.

I find it quite odd that Adobe has not published a profile yet. I've never encountered this before with dozens of lenses.
do you notice very strong, basically unrecoverable vignette in the corners shooting at f/8 with this lens on a light background? I'm on my second one of these lenses and both seem to suffer from the issue. Must be a design flaw

Well bless adobe they finally added the profile in Lightroom Classic 10.1
