The Canon rangefinders of the late 1940s and early 1950s are Leica-compatible screw-mount cameras. Many were brought to the U.S. by servicemen who bought them while visiting Japan during the Korean War. Typically these were mounted with a 50mm Serenar (later, Canon) lens. Many of these can still be used, and are similar in function to the Leica ...
