The Konica Hexanon AR 1.2/57mm was built in two main versions, the older one with metal focusing grip, the newer with rubber focusing grip. Both main versions share the same optical construction, and both have radioactive thorium glass. As nearly all f1.2 lenses also the Hexanon is quite expensive, even though it is not really a rare lens. Prices are in the range of CHF/EUR/USD 500.--.
