If you use Lensfun <= 0.2.8, write the following into ~/.local/share/lensfun/sigma.xml: <lens> <maker>Sigma</maker> <model>Sigma 8-16mm f/4.5-5.6 DC HSM</model> <mount>Sigma SA</mount> <mount>Canon EF</mount> <mount>Nikon F AF</mount> <mount>Pentax KAF</mount> <mount>Sony Alpha</mount> <cropfactor>1.5</cropfactor> <calibration> <!-- Taken with Nikon D7100 --> <distortion model="ptlens" focal="8" a="0.00985" b="-0.07668" c="0.09452" /> <distortion model="ptlens" focal="9" a="-0.0073" b="-0.00074" c="-0.00329" /> <distortion model="ptlens" focal="10" a="-0.00608" b="-0.00881" c="0.02021" /> <distortion model="ptlens" focal="12" a="-0.02662" b="0.07817" c="-0.08027" /> <distortion model="ptlens" focal="14" a="-0.01289" b="0.0306" c="-0.01315" /> <distortion model="ptlens" focal="16" a="-0.0184" b="0.05749" c="-0.04454" /> <tca model="poly3" focal="8" br="-0.0000141" vr="1.0001963" bb="-0.0000573" vb="1.0001735" /> <tca model="poly3" focal="9" br="0.0000277" vr="1.0000937" bb="-0.0000535" vb="1.0002340" /> <tca model="poly3" focal="10" br="0.0000257" vr="1.0000862" bb="-0.0000679" vb="1.0002823" /> <tca model="poly3" focal="12" br="0.0000717" vr="1.0000453" bb="-0.0000847" vb="1.0002906" /> <tca model="poly3" focal="14" br="0.0001034" vr="1.0000726" bb="-0.0000992" vb="1.0002334" /> <tca model="poly3" focal="16" br="0.0001132" vr="1.0001441" bb="-0.0001015" vb="1.0001906" /> </calibration> </lens> Tschö, Torsten. -- Torsten Bronger Jabber ID: [email protected] or http://bronger-jmp.appspot.com ------------------------------------------------------------------------------ Meet PCI DSS 3.0 Compliance Requirements with EventLog Analyzer Achieve PCI DSS 3.0 Compliant Status with Out-of-the-box PCI DSS Reports Are you Audit-Ready for PCI DSS 3.0 Compliance?
