The Rolleimeter uses the superimposed image principle and is actuated by and coupled to the moving front panel of the camera. It is attached to the nameplate directly in front of the direct view finder. A vertical glass rod with focusing spot far the two images can be seen when lacking through the tinder. Focusing the camera by superimposing the two images so that the outlines exactly coincide insures sharp focus. Framing and focusing are accomplished while looking through the tinder, without making the eye train one position to another.

*Missing focus ring collar for focus adjustment, please ask our tech to assist in calibration before use.
