Pentax vs Takumar/ Super Takumar

For a while after the Pentax K bayonet lens was introduced Pentax carried on producing lenses under the Super Takumar/Takumar name with both Pentax K and Ka fittings. Can anyone tell mne the difference between Pentax and Takumar lenses with the K and Ka fittings? Is there any difference in quality?

Takumar, Super Takumar and Super-Multi-Coated (later just SMC) Takumar lenses were for the screw thread Pentax cameras.

The K bayonet lenses were originally SMC Pentax, follwed by SMC Pentax-M and then SMC Pentax-A. The A series saw the ressurrection of the Takumar name, but this time as SMC Takumar-A lenses, a lower cost alternative to the SMC Pentax-A range.

Typically, these had simpler construction (fewer elements) and simpler coatings. The quality was excellent, but not up to the same high standards as their more expensive versions.

Thank you for your help, it confirmed what I half believed.
