Legacy lenses on EOS R: Canon FD 50mm f/1.2 'L' lens review with samples

On rare occasions I get tempted to test out particularly interesting legacy lenses (I don't often have the time to cover many of them, though). This very bright standard lens from 1980 still attracts high prices on eBay - how usable is it when adapted onto a Canon EOS R?
