I picked this lens up cheap, as a second M50 f/1.4, and there is something wrong with it... not sure what. Everything is out of focus, and very very saturated. This is RAW and developed in lightroom. But, I decided to keep it, as it is a pretty cool effect. You can see that the white and highlight and saturated areas kinda bleed outward, but it looks kinda like a painting... I was focused perfectly at the time of the shoot.

Now here's from my main M50 f/1.4 to show a comparison with a properly working copy. I've had this copy since 1980.
Toronto Distillery District (AKA coffee and muffin district, go ahead and try to find some whiskey there)
I also have a M100 f/2.8 (a newer lens I got in 1981 and my favorite lens), M135 f/3.5 (got this one for $40 at cameta a week ago, haven't shot anything worth posting yet), M85 f2.0, M200 f/4. and looking for more, probably a 28, a backup M100 f/2.8, maybe a M120 f/2.8 (? don't know much about this lens)
