The best lens for the GH5s*

The Panasonic GH5s is a great camera - small/portable, easily accessible features, loads of video options, etc. The functional continuous AF (thanks to the hack described by YodaYeo) makes it the (almost) perfect travel camera. It has a few shortcomings though (primarily the lack of IS). Finding the best lens to pair with this camera is critical. For the reasons described, I believe the best lens for this camera is the Pana-Leica 12-60mm lens.
