>>4114501>Takumar 50mm 1.4Those are really nice lenses if in good condition. They go yellow or even varying shades of brows over the years, but the yellowing can be removed by blasting it with UV light for a week.
The smaller and lighter Super-Takumar 55/2 is at least as good as the 1.4 and better yet, it doesn't have any radioactive glass elements (=no yellowing problems).
