Beautiful Asahi Pentax Super-Takumar 50mm f1.4 lens (sn: 1377361) with a Berolina 2x converter, an empty filter case, all signs from my internet research point to 8 elements and 6 aperture blades, see photos for details.

I tested the lens manually and could not find issues, focusing works smooth, aperture can be set easily.
No scratches or fungus on the glass.

Front and back lens caps and original lens hood included.
