Does anyone know anything about this lens? I'm going to guess by the serial number (and how it flares when you point it into the sun) it was made in 1972. I cannot get over how sharp it is, almost no color fringing. I have seen it branded as a Rikenon lens in M42 mount as well, I have a Nikon mount version. Everything I look up points to the later f3.5 version. It takes 72mm filters and it typical Japanese heavy metal construction. Very little distortion.
