Asahi 300mm f4 Takumar brand_Fed dispensing with the multiple helicoidsThe Asahi 300mm f4 Takumar is an old school, manual diaphragm M42 lens not even a preset system on this one. But image quality is very good, and the glass is clean and clear. Light cosmetic wear: mostly a slight deformation of the rubber grip on the aperture ring. A nice classic telephoto lens.
