Canon EF

Beautiful black Canon which debuted in 1973. It's the only FD-mount camera body that utilized the Copal Square shutter. It was the first from Canon to have built-in Shutter-Priority autoexposure. It had the widest range of shutter speeds available at the time, which was 1/1000 sec all the way to 30-secs. And it uses a voltage-regulating circuit. Which means we can put modern batteries in it, and it will work just fine!
