The term "Canon 7" generally refers to a rangefinder camera produced by Canon Inc. The Canon 7 was introduced in 1961 as the final model in the Canon rangefinder camera line, preceding the company's full commitment to Single Lens Reflex (SLR) cameras.
Key features of the Canon 7 include a built-in selenium light meter, a bayonet lens mount compatible with Leica's M39 (L39) screw-mount lenses via an adapter, and a bright viewfinder with parallax correction. It offers shutter speeds from Bulb (B) to 1/1000th of a second. A distinctive feature is its multi-frame viewfinder, showing frame lines for 35mm, 50mm, 85mm, 100mm and 135mm lenses, offering flexibility to photographers using different focal lengths. The Canon 7 is typically considered a robust and reliable camera, popular for its ease of use and versatility, even by modern standards. It was followed by the Canon 7s and 7sZ, later iterations with further improvements.
