it depend what you expect from this lens.
You can adapt it for Sony, using same adapter as with Swirly Helios.
This Takumar is not highly valued lens for its optical performance, but as each Takumar, it is very well made.
I would suggest you to look for Topcon RE Topcor 58/1.8 instead, as that lens is much sharper and had quite interesting rendering. I can offer you few alternatives from Carl Zeiss Jena – Very good Pancolar 50/1.8 MC (around 100-120 USD), Old but charismatic Pancolar 50/2 zebra (50-80 USD), Meyer Optik Gorlitz Trioplan 50/2.9 (100-150 USD), Super cheap Pentacon 50/1.8 (if you just want to try that focal length/speed combination,(up to 25 USD) and few other (There are some great Russian alternatives as well). You might also consider Olympus 50/1.8 (be sure it has “Made in Japan” engraved on the lens collar, Or Nikon 50/1.8 Ai (or Ai-S, but not E)
Among Takumars, most popular are 50/1.4 versions, but except very first (8 elements) version, they all have Thoriated (radioactive) elements inside which are yellowing in time. To bring them to their original transparency, you will need UV (black light) lamp to keep shining on the lens for many, many days or months.
