You may want these as well while I think of it:
Optical formula 1957 Takumar 58mm f/2
Optical formula 1964 Super-Takumar 50mm f/1.4
Notice the cemented triplet with curved surfaces in the Super-Tak - very difficult and expensive to manufacture and it's said Asahi lost money on every copy sold; hence it didn't last very long. This was meant as a Planar-killer and once its crown had been awarded by the press the simplified 7/6 version was quietly ushered in (before the 8/6 crippled Asahi's finances).
