In the early 1950's it was a matter of prestige for a leading camera company to have its own fast telephoto/ portrait lens.

It was the time when CARL ZEISS (1938) offered its great BIOTAR, a 6-elements/ 4-groups design with the highest speed of f/1.5 75mm, a quite huge, hevyweight lens that was soft wide open. Also LEITZ had a SUMMAREX 1.5/85mm since 1943 - 7 elements in 6 groups, a complicate design for the coating technique of its time, therefore flare-prone and quite heavyweight as well - 700g.

Another curious find, although most people think that all Takumar and Pentax 1:1.8 (and 1:2.0) 55mm lenses have the same optical design, is this unlikely because some of them have radioactive glass and others not.
