This is an excellent news about LensFun evolution, to be able to
backport Adobe files as well. This will increase the lens model/maker
list a lots.

This want mean that legally, we will able to distribute and use
converted files through LensFun project without any problems with
Adobe ?

> Digikam uses the Lensfun library for lens correction.
> The Lensfun repository now contains a branch "acm" which implements
> the Adobe Camera Model for distortion (including fisheye), TCA, and
> vignetting.  Moreover, it contains a script that converts LCP files
> into Lensfun XML.  It merges the two data sources, so you get one
> big database.  It can even combine LCP and Lensfun correction for
> the same lens model.  You may compare
> http://wilson.bronger.org/lensfun_coverage.html with
> <http://wilson.bronger.org/lensfun_coverage_lcp.html>.  See
> http://wilson.bronger.org/lensfun/lensfun-convert-lcp.html for more
> information.
> You can clone the git branch with
>     git clone -b acm git://git.code.sf.net/p/lensfun/code lensfun-acm
> or download a tar ball with
>     wget http://wilson.bronger.org/lensfun-acm.tar.gz
> This Lensfun will print on stdout whether an "acm" model was used
> for correction, so that you know whether LCP or Lensfun data is in
> action.  Please give us feedback about the functionality and
> accuracy so we can evaluate this possible addition.  If you have
> access to a Lightroom or Photoshop version, please try to compare
> the results.  You may use Lensfun's bugtracker for feedback.  Thank
> you!
