I have used many manual focus lenses on Canon mount. They are all bad, whether it's Zeiss, Leica R, Canon's 50mm L1.2, 24-70/2.8 L, or 70-200/4, I found the problem in Canon's focusing system.

You don't say why manually focusing is bad. Care to expound?

It has something to do with the design of the focusing screen, at least. If you look up bhphoto.com for Canon's the focusing screen, you'll find which screen is best for (critical) manual focusing. I found none are satisfactory, but I guess I lost my patient before I put in enough practice. It might improve.

I also found the same lens could perform differently on different cameras (same model, different sample, shoot in the store). It's all due to the focusing. There was no live-view focusing assistant at that time. With today's live-view, it might help.

I have never been able to focus with the viewfinder, not even the old film era split prism. Until live view and or MA (which allows me to fix the Canon factory designed front focus is better issue) I was never able to focus period.
When you can't focus, nothing else matters
Once you can, everything else does.
