I just received my Sigma 18-35 and love it. I use Lightroom for editing and according to Adobe, the Sigma 18-35 f 1.8 is supported. When I go to lens correction, I don't see the lens available.

Do you have to manually add the Lens profile? If so how do you go about doing this? I can't find anything when I search around.

You can either wait for Adobe to add it in an update, or if you can't wait you can download the Lens Profile Downloader. If the lens profile isn't available yet you can make your own with the Lens Profile Creator. Both are available to download from Adobe here.

  • \$\begingroup\$ Adobe says it is supported helpx.adobe.com/x-productkb/multi/… however when I go to Lightroom 5.5, lens profiles, I only see sigma DC 4.5mm, 18-200, 8mm, 12-24 and the 15mm \$\endgroup\$

  • \$\begingroup\$ What brand of camera are you using? Also, have you tried using the tools I linked to in any case? \$\endgroup\$ Commented Jul 15, 2014 at 14:23
  • \$\begingroup\$ Yes I tried the lens profile downloader, it has the same profiles as I stated in the previous comment. I'm shooting with a Canon 70d. \$\endgroup\$

  • \$\begingroup\$ I have the 18-35 1.8 in Lightroom 5.5 (Camera Raw 8.5), but not in the Downloader. Weird. Is your version of Lightroom fully up-to-date? \$\endgroup\$ Commented Jul 15, 2014 at 15:04
  • \$\begingroup\$ I just installed LR 5.5 from Creative Cloud. I went in and checked for a software update and it said I am all up to date. I'm pretty sure I'm looking in the correct location as well. Under develop / lens corrections / profile... enable profile corrections Make: Sigma Model: lenses stated above \$\endgroup\$

There is a readme.txt at both



C:\Program Files\Adobe\Adobe Lightroom Classic\Resources\LensProfiles\1.0\ThirdParty

that reads

Install third-party (non-Adobe) lens profiles here.

By default, .lcp files are saved to


I left my original file in AppData and then copied that file to both these locations. I didn't investigate which location Lightroom is dependant upon, but Adobe keeps identical lens profile directories on my computer; adding to their file clutter worked for me.


I figured it out, the photos have to be shot in RAW. I was editing trying to edit via jpg that was shot on the 70d with the sigma 18-35. Thanks for you help @ElendilTheTall
