This is a Canon Demi C, a half-frame viewfinder camera from 1965. In addition to shooting 35mm at half-frame (giving you 72 shots from a 36-shot roll), it is an uncommon camera in that it comes with two interchangeable lenses unique to this camera. There’s a 28mm ƒ/2.8 lens, and a 50mm ƒ/2.8 (attached), which behave as 50mm and 75mm lenses, respectively, on this camera. The lightmeter on it works, but I haven’t tried it out yet.
