>>4269990>I'd rather buy a new obscure Chinese lens for $200-400The thing is that they're just better than vintage shit floating around. They have all the coatings, manufacturing is of surprisingly high quality:
nothing is loose,
no scratches,
no fungus,
exotic aperture blade designs,
all metal,
modern glass manufacturing,
soul,
old lens schematics
Stop down these f 0.9 lenses to f 2.8, and you get image quality that beats japanese glass that's ten times more expensive.
