Remember, that for Canon, there was the Great Schism. Pre EOS was dropped and made incompatible in 1987. Everything EOS is upwardly compatible, even to mirrorless. And now, against all odds and expectations, all those dusty and forgotten FD / FL lenses are 'hot' again when adapted to mirrorless. There's isn't this unending F-mount worship, in the Canon line-up, due to that 1987 Canon decision.
