There are a lot of Sigma leneses, which are reported as Sigma only. See eg: Subject: Re: [Lensfun-users] Adding new corrections and creating corrections from user submissions Date: Thu, 14 Jun 2018 23:44:14 +0200 The first problem is, that the dt-repo for the latest Ubuntu 18.04, doesn't contain an exiv2-version, which supports this. The 2nd problem is, that lensfun uses this recognition and how lensfun-corrections has to be defined in such a case.
