I am using LRC release 11.3.1 with Camera Raw 14.3. I have imported some astro photos from the camera and switched to the develop module. In the lense corrections under the profile tab I checked remove chromatic aberation adnd enable profile corrections. Setup is Auto. My lense is not available in the Lens profile drop downs. It is a SIGMA 28mm F1.4 DG HSM lense. The adobe support webpage (Supported lenses (adobe.com)) Shows this lense as being available:
SIGMA 28mm F1.4 DG HSM A019
Canon, Nikon F, SIGMA, Sony FE
8Minimum Lightroom Classic/Camera Raw/Photoshop version required.
The drop downs offer very few Sigma lenses, all older, specifically:
dp0 through dp3 quattro, two DCs and three DGs, the DGs are 8mm, 12-24mm and 15mm.
I am running this on windows 10 on a 7 year old machine with an old Lightroom 5.7 installation still on it, but I would think that should not matter. If it does I could blow the old installation away, but want confirmation that it is truly necessary and will fix the issue.
