Originally posted by i_trax I updated to 5.6 , loaded some photos taken with K-3 + Sigma 18-35 1.8 and.......it is not in Lens Profiles options, I only have 2 Sigma DC's 4.5 + 18-200
how do you enable more profiles?
The lens profile for the Sigma 18-35/1.8 should be there (C:\Program Files\Adobe\Adobe Photoshop Lightroom 5.6\Resources\LensProfiles\1.0\Sigma\Pentax\PENTAX (SIGMA 18-35mm F1.8 DC HSM A013) - RAW.lcp), but not auto-detected on import. In the Develop module, scroll down the right pane to Lens Corrections section and click Profile. Click Enable Profile Corrections and choose Sigma from the drop-down for Make. The profile for the 18-35/1.4 should auto-fill.
I have a similar problem with the Sigma 17-70/2.8-4.0 (C). I would love to have it auto-detect on import, but so far the solution has eluded me.
