This is not surprising. Most of those fast chinese lenses are old double gauss (Biotar/Planar) formula lenses that has been used for probably a century, but with a built in speedbooster/focal reducer at the back end. That's how they get those fast speeds and poor wide open image quality.

Yep nothing really new under the sun.  This looks all awful lot like a few tweaks on the Zeiss original Planar design which dates back to the 1930's.
