Manual focus 35mm folding rangefinder camera released by Kodak in 1957. This model, often referred to as the "Big C" variant, improved upon the IIIc (small c) by enlarging the viewfinder and adding parallax-corrected framelines for the accessory 35mm and 80mm lenses. Some IIIC models do not have this upgraded viewfinder. Retina rangefinders could be found with either Rodenstock or Schneider-Kreuznach lenses and can only accept accessory lenses from the same manufacturer. It has an uncoupled selenium cell light meter without the cover of the IIIc. Metal body available in silver.
