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

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
