Purpose: An optical coupled range finder for use with the direct view finder of the Rolleiflex particularly suitable when shooting sports or flash pictures in poor light,
Description: 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.
Before using the Rolleimeter two simple adjustments are required:
1. A one time adjustment of the actuating lever (screw a) to suit the focal length of the lens employed.
2. Adjustment of the lever button (screw b) so that the range finder indicates sharp focus at infinity (oo) when the camera is in focus at the same distance. This adjustment should be rechecked from time to time.
So that’s what they’re for. Excellent.
