Question

Sigma 85mm 1.4 dg dn lens correction

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.

    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.

        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.

        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.

          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:

          https://feedback.photoshop.com/conversations/camera-raw-and-dng/camera-rawlightroom-lens-profile-requests-and-information/5f5f45a84b561a3d4258a112 

           

          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.
