HHhhhmmm, Lenstagger stopped working for me on OS X. San Francisco ahead of the Super Bowl. Contax G90, a7rm2.
EDIT: BTW, if you use OS X 10.11.3 and Lenstagger stopped working, try changing the path in the plugin to : /usr/local/bin/exiftool - this fixed the problem for me. The author plans to update the plugin when he gets a chance.
