Konica's AR medium tele — the 200mm f/4 Hexanon for wildlife and sport.
The Konica Hexanon AR 200mm f/4 was a medium telephoto prime for the Konica AR bayonet on the Autoreflex system. At 200mm it offered the longest reach among Konica's more common AR primes, aimed at sports, wildlife and distant subjects.
This is a manual-focus Konica AR lens with a 200mm focal length and a maximum aperture of f/4. It is a telephoto prime giving a narrow field and strong perspective compression. Optical construction, filter thread and minimum focus distance are not verified here and are left out rather than guessed.
A 200mm f/4 brings distant subjects closer and compresses perspective strongly, which suits wildlife, field sports and candid work where you cannot approach the subject. Its moderate aperture keeps the lens reasonably compact for its reach, making it manageable for handheld daytime shooting.
The 200mm f/4 Hexanon is a fairly common AR tele available at modest prices. Inspect the elements for haze, fungus and coating wear, confirm the aperture is dry, and check the long focus helicoid for even resistance. It adapts to mirrorless via an AR adapter, where its reach is easy to use manually.
