I use 28, 50, 90 M-Hexanons, as well as CV Nokton 35/1.2 as well as several LTM lenses with Leica adapters - Canon 50/1.2, Summitar, J-9, Nikkor 105/2.5, etc on my Hexar RF. I also used ZM Planar 50, Rigid Summicron, current Summicron 50, Leica Fat TE 90 on it and never had any issues with patch/focus. Go figure.
