The Leica SL (Type 601) was launched in October 2015. Fullframe sensor (24MP) and electronic viewfinder with 4,4MP (!) Of course with L-Mount Here is a video of Hugh Brownstone about it:
It seems price of SL has dropped to £3195 https://www.macfilos.com/2019/04/26/leica-sl-prices-plummet/ which means second hand price will also drop. Maybe time to pick up a second body?
