Just recently went all Leica M. Even for my professional work.
Picked up an new M 262 and a gently used M-E and a mid 1980s 90mm Summicron and had besides my Lux FLE a Zeiss 35 2.8 Biogon C. I bought the cameras and the lenses at Tamarkin Camera. The best to do business with. Dan Tamarkin and Ernie are just terrific.
Sold all of the Canon gear.
