I was trying my wife's macro lens on my camera just to know if it would be worth to buy a "smart" adapter for Canon lenses on my Fuji X-T20. Now I am using a cheap "dumb" adapter with no control of the aperture and only manual focus. It looks like it would be worth it. ;)
This macro of a coltsfoot was focus merged of 8 shots in Affinity photo, and further edited in Luminar as a plugin.
