    Overview

    The Cosinon 200mm f/3.5 is a solid metal, heavy M42 lens often rebadged as Vivitar, Soligor, or Panagor. Optically, it is soft wide open, especially in daylight, but improves when stopped to f/8 or f/11; bokeh is mediocre. On DSLRs, it exhibits purple fringing, though on Super 16 sensors the fringing is less noticeable. Build is robust but heavy, requiring careful handling. It suits budget-conscious photographers seeking a telephoto prime for low-light or moon shots, accepting its optical compromises.
