I have a Pentax K50 and the Sigma 17-70 and the Sigma 70-300 OS. For pictures with the Sigma 17-70 all Sigma lens profiles are displayed. The Sigma 70-300 OS only a few but not the needed. Why is that?
If profile may only be compatible with raw files. Check whether the photos that the profile is available for are JPEG
Thank you for the quick answer.
