Canon III is a 35mm film Rangefinder camera and manufactured by Canon Camera Company, Inc. Tokyo , Japan. The Canon III is a very close copy of a Leica IIIc. [1] But there are some differences, mainly Canon's combined view/rangefinder which surpasses the Leica, straight body edges, and lots of other technical features. Its finish is fully up to Leica standards. There are some 500 individual camera models originate from about 21 original Leica inspired cameras. Many of these were prototypes or produced low numbers. Main brands that produced large quantities are FED, Minolta 35, Nicca, Yashica YE, Zorki, and Canon III.

Notes and referencesEdit

  1. Canon Leica-copy rangefinder in Marc Rochkind's site
  2. The early Leica cameras, and almost any other Leica inspired cameras that winding on also causes the film speed selector to turn, always cock the shutter before changing film speeds.
