It's so fun to shoot with now.
I enjoyed with the Canon 5D "Classic" with an alternative focus screen, although the 12MP sensor didn't take advantage of it. When I upgraded to the Canon 5D Mark III the manual focus lens fun ended due to no interchangeable focus screens.
The Canon EOS R has brought the fun and results back. The rendering and bokeh on this lens are so amazing... especially considering how much smaller it is than the Canon 200mm f/2L IS which is the only lens that brings similar results, in my experience.
Mirrorless has made shooting DSLR lenses so much more reliable too—focus can pretty much be guaranteed via magnified Live View and even unmagnified it is probably bettr than today’s horrible DSLR focusing screens.
