Jump to: navigation, search

The Canon Demi is a 35mm half-frame viewfinder camera with a very high quality production standard. It was launched in 1963. It offers easy operations without the use of batteries, the lightmeter is a selenium cell.

Users can choose from symbols on the focus ring to determine distance from the subject. The outer ring is designed to operate a combination of aperture and shutterspeed.

By looking at the needle of the lightmeter, the photographer can match the second needle by turning the outer ring. The camera then uses a combination between f/2.8 and 1/30 sec and f/22 and 1/250 sec. for ideal exposure.

It was sold as a kit with a softcase, wrist strap and lenscap. There was a small flash available which uses AG or PH bulbs, the Canon J-3.
