How to add the Sigma 14-24 f/2.8 in Lightroom 6 as a new lens profile?

Sorry, but you can't. The lens was first supported in LR Classic 7.3, so the only way to have a version of LR with a profile of the lens is to sign up for the Adobe Photographer's Plan subscription.

The final update for Lightroom 6 was 6.14. There will be no more updates or upgrades for Lightroom 6.

It is possible to use an adobe lens profile from a newer version of LR in an older version of LR by copying the DNG Converter version of the lens profile to the Users profile area.

If you're on Windows, you can download and install the latest DNG Converter (currently 10.4) from:

Adobe software and product updates

then go to:

C:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0\Sigma\Sigma

and copy

SIGMA (SIGMA 14-24mm F2.8 DG HSM A018) - RAW.lcp

to your Users third-party profile area:

%APPDATA%\Adobe\CameraRaw\LensProfiles\1.0\Downloaded  (create folders if they don't exist under CameraRaw)

Note:  this folder path is equivalent to:

C:\Users\**username**\AppData\Roaming\Adobe\CameraRaw\LensProfiles\1.0\Downloaded

but the AppData folder is hidden so you'll need to turn on show hidden files in Explorer or just type it into the Explorer address bar and hit Enter but it's easier to use the system alias %APPDATA%.

Restart LR.

If the lens still doesn't show up it may be that the A018 is different or the lens profile appears to only be for this Sigma lens on Sigma cameras, based on the path where the original lens profile is found.

Are you sure this works the way you describe? I find this odd for two reasons:

1: Why would the DNG Converter install lens profiles in the first place? It doesn't need them at all. I can find camera profiles inside the installer package, but not lens profiles.

2: Why would you have to copy these profiles from the root folder to the user folder? All the lens and camera profiles that are supplied by Adobe belong in the root folder, and this would be just one of those profiles. Lightroom should be able to use the profile from there.

I renamed the LensProfiles folder then ran the installer for DNGC 10.4 and a new LensProfiles folder showed up with 360MB+ of almost 1900 files which is identical to the contents, in number and size of files, of the prior LensProfiles you can see renamed, before I ran the installer.  If you watch closely, you *may* be able to see the .lcp files being installed after the .dcp files as the installer runs.  I recognized the word "aspherical" once but it goes so fast.

The DNG Converter installs things for Photoshop's ACR and the DNG Converter, itself, when it creates DNGs and embeds the Adobe Standard profile.  LR's lens and camera profiles are elsewhere.  People pay more for Photoshop and it may be Adobe's thinking that they deserve to see all the camera and lens profiles even if their ACR version is older and requires a DNG Converter.  I don't have an older PS on my computer to see what actually happens in ACR in that older PS, if lens profiles are available for newer lenses or not.

Interesting. Maybe there is indeed a philosophy behind it, or maybe it's just sloppy programming and they just took everything that is installed by Camera Raw and added that to the DNG Converter installer too. My guess would be the latter...

[ssprengel]

The "programmers" are distinct from the "install-package-makers" I'm pretty sure, based on a comment from an insider years ago about how the engineers (who used to sometimes answer questions, here) weren't very happy with the installer team.  It may be a simplification to avoid problems, which I guess you could label "sloppy" but when the technical teams are in various parts of the world it may be a necessarily simplification.

And I'm pretty sure that for quite a while for mirrorless (micro4/3) cameras with built-in lenses, Adobe was legally obligated to never show an uncorrected raw, but you can find .lcp lens profiles for the very first mirrorless cameras, so Adobe may have required lens profiles to be included with the DNG Converter just to make sure the data was available to be used.  Now the profiles for mirrorless cameras are internal, not .lcp-file-based, but I'm not sure what happened with the first release or two of LR after the first mirrorless was supported.

ssprengel is right. This indeed works. You can use lens profiles and camera profiles from dng converter in earlier versions of Lightroom. This is a bit of a hack but works.

1. dng converter indeed does this and it is one of the reasons why the download is so gigantic. No clue why it does this but it does.

2. Adobe used to support user profiles in the root folder in older versions of Lightroom but now it only reads them from the application package and from the user folder. No clue why they changed that and indeed not logical.

I trying to find a lens profiles hat would equal to my Sigma 14-24.. what do you think?

[ssprengel]

Are those camera-jpgs or did you get the lens profile to work as described, above?
