Rangefinder

The rangefinder camera type category is for cameras which use a split image rangefinder to set the focus. In these cameras, a dial is adjusted to bring two parts of an image into alignment at the point where the subject is situated.

In some cases the rangefinder is coupled to the focusing system of the camera, so as the rangefinder is adjusted the focus is set, and in some cases the rangefinder is used to set the focus distance on a scale, which is then applied to the camera’s focus adjustment.
