darktable 1.4-2 amd64 (Xubuntu 14.04 - Trusty) Sigma 8-16mm F4.5-5.6 DC HSM (Pentax) is not found in the lens correction menu, but /usr/share/lensfun/slr-sigma.xml contains this lens.
According to http://wilson.bronger.org/lensfun_coverage.html there are 2 crop factors: 1.613 and 1.534. AFAIR the crop for Canon is bigger, so maybe I have to change the xml-file? What do I have to do, to see this lens in the DT-menu?
