A rangefinder camera is a photographic camera equipped with a coincident-viewing distance-determination apparatus, called rangefinder, which permits the photographer to assess the subject expanse and take images that are in pointed focus. The majority of rangefinder cameras show two images of the same subject, one of which moves when a calibrated wheel is turned. When the two images coincide and fuse into one, the expanse can be read off the wheel. This is called connected rangefinder. Such rangefinders have been used in 35mm cameras, such as those made by Leica, Canon, Nikon, and others for numerous years, and also in larger-format cameras such as medium format bending cameras or rigid cameras like the Mamiya 7, and even some early Polaroid cameras.
Non-coupled rangefinder cameras brandish the focusing distance and require the person taking photos to move the worth to the lens focus ring; cameras without built-in rangefinders could have an external rangefinder fitted into the accessory footwear. previous cameras of this type had separate viewfinder and rangefinder windows; subsequent the rangefinder was incorporated into the viewfinder. More up to date concepts have rangefinders coupled to the focusing means, so that the lens is focused rightly when the rangefinder images
