SLR camera with exposure flash exposure and/or auto-focus sensors - uses sensors allowing any selected point n viewfinder to be individually measured

摘要

The camera has exposure, push exposure measuring sensors and/or an autofocus-range finding measuring sensor. The image point to be measured by these sensors can be freely chosen by the photographer in the viewfinder. The selection of the point to be measured is entered by an input appts. The point selected is shown in the viewfinder by an imposed marking. The point can be selected by a spherical roller serving as an extension to the release button (1). The selected point can be indicated via a ground glass plate (3) in the camera or a transparent liq. crystal display (4). ADVANTAGE - Avoids faulty exposure measurements arising when subject of interest is not in the middle of the viewfinder where measurements are usually made by the sensor(s).
