Unless, of course, you have already made up your mind.

Thank you for the link and the concern.
As I understand it Bastian complains that these lenses perform poorly on Sony cameras because Sony has a thick "sensor glass" that causes blur in the corners. The RF version is specifically tuned for the Canon sensor. I will get much better corner sharpness and less "smearing" on any RF body than what you see in the Sony-adapted sample photos in these links.
The VM versions in the links are "dumb" lenses with no electronics. The RF version has data contacts. So I'll enjoy...
- Focus Guide (Green box or "three triangles") focus assist making f/1.0 much easier to hit than the reviewer's experience. I've used this godsend of a feature with the ZEISS Classic ZE manual focus that I have.
- EXIF Data that actually records "f/1.0" which the M-mount version cannot do.
- Automatic IBIS as the lens tells the camera its focal length so my RF body’s stabilization will work like any other RF lens with AF without digging into the menu and telling the body that I attached a manual focus 50mm lens.
- The M-mount version is limited to 0.9m minimum focus distance. The RF version can focus closer @ 0.45m. This makes the f/1.0 "blur" effect even more dramatic for detail shots.
I was purposefully looking for the most desirable 3rd party RF lens and the Nokton 50mm at f-one-point-zero fits the bill. Given the price has dropped from $1799 to under $1049 makes it an easy yes especially when used price
dropped to $1029.
For those reasons alone are why I'm not open to getting any further non-RF native lens. Never had any M mount system.
If I were to go with a 50mm f/1.2 then I'd rather get a RF 50mm f/1.2L USM that goes for
292,500JPY. This $840 extra over the f/1.0 gives me quality of life improvements of
- modern optical perfection vs vintage character
- CA is largely gone
- fast & decisive AF
- 0.39m MFD
- weather sealing & durability
- Face and Eye Tracing AF
- in-body DLO, difraction correction, peripheral illumination correction (vignette control), distortion, focus breathing correction & other lens correction
- Control Ring that can be programmed with ISO, exposure compensation or aperture directly
Never had the EF 50mm f/1.2L USM due to its reputation at f/1.2. IIRC it was voted the optically "worst" EF L lens in production of the last decade before RF mount was introduced. This led me to the ZEISS Planar 50mm f/1.4 ZE in late 2008. Today's RF L successor made heads and shoulders improvements over the EF L.
Was scouting for image samples of the
EF 50mm f/1.0L USM on the R1 but it was pointed out to me that Nokton 50mm f/1.0 selling for under $1049 brand new may be a better option.
Having said all that I may have convinced myself to get the RF 135mm f/1.8L IS USM for
277,200JPY as I've never had a 135mm and over $327 cheaper than
BHPhoto. Been dreaming of the Sony Carl Zeiss Sonnar T* 135mm f/1.8 ZA for over a dozen years when Canon was stuc kat f/2.0 with their EF 135mm. Although I wish Canon went the extra mile and matched the Sigma 135mm f/1.4 ART that goes for
261,000JPY that is over $231 cheaper than
BHPhoto
