The Canon F1 is a flagship camera released in 1971 and in production until 1981. Built of brass and glass, it’s a tank! Fully mechanical (no battery required), it’s built to endure 100,000 shutter cycles, temperatures ranging from -22F to 140F, and 90% humidity. The camera below is nearly 50 years old and is fully operational. They don’t make them like this anymore.
