The Canon Demi C is a half-frame camera produced by Canon and introduced to the world in April of 1965. The Canon Demi C makes an 18x24mm frame, giving the user about 72 exposures on a standard roll of 36 exp film.
Unlike its predecessor, the Canon Demi, the Demi C is capable of using different lenses. The Demi C uses a proprietary thread-in lens mount and Canon made two lenses for this camera: a 28mm f/2.8 and a 50mm f/2.8. Since the frame is half the size of normal, the standard lens for the Demi C is the 28mm while the 50mm serves as a telephoto portrait lens. The viewfinder for the Demi C naturally fits the 28mm lens but has smaller framelines for the 50mm as well.
The Demi C has a built-in selenium cell lightmeter and uses a needle readout atop the camera. One changes the shutter or aperture settings on the camera til the top readout confirms correct exposure. Meanwhile the Demi C lacks any sort of focusing aid as it is a viewfinder camera only. Focusing is done via distance scale on the lens barrel.

Tony Rosenwald's Canon Demi C
This unassuming little Canon Demi C is just one camera in a massive consignment we brought into the shop in 2017. It is a pretty incredible collection of equipment that is matched only by the story of the man who owned all of it. The progenitor of all this camera excitement is a man named Tony Rosenwald.
Anthony Richard Rosenwald was born in Chicago in 1937 into the prominent Rosenwald family. His great uncle was the prominent Julius Rosenwald: an influential businessman and philanthropist. The Rosenwald family is considered a founding benefactor of the National Gallery of Art, they even have their own gallery. Tony's family also donated millions in support of education for African Americans and created a foundation in the 1930s to help support education in Black communities. These funds helped thousands of people, including the influential American novelist, Ralph Ellison, who would later give heavy praise and thanks for the opportunities the Rosenwald foundation helped him realize...but back to Tony.
Tony got his start in photography at the age of 12 when his mom bought him a portable darkroom he could set up and use on the train trips he made to and from boarding school. During the long rides back and forth, Tony got to know many of the porters on the train. He started making portraits of them and then would set up his darkroom, develop the film, make proof prints, and give each of the porters a print by the time the trip had concluded.
