    Abstract: A photographic apparatus, particularly a still camera, wherein the upper right-hand corner portion of the front wall of the body supports a knob whose stem is confined to movements in a twodimensional field. Vertical movements of the knob result in adjustments of the diaphragm, horizontal movements of the knob result in adjustments of the shutter, and movements of the knob in any other direction result in simultaneous adjustments of the shutter and diaphragm. The positions of the knob are observable in the view finder, and the knob can further rotate the moving coil instrument of an exposure meter so that the needle of the instrument moves with reference to stationary markers to indicate whether or not the selected combination of exposure time and aperture size is satisfactory for the planned exposure.

    Abstract translation: 一种照相装置,特别是静态照相机,其中身体的前壁的右上角部分支撑一个将茎限制在二维场中的运动的旋钮。 旋钮的垂直运动导致隔膜的调节,旋钮的水平运动导致快门的调节,以及旋钮在任何其他方向的移动会导致快门和隔膜的同时调节。 旋钮的位置可以在取景器中观察到,并且旋钮可以进一步旋转曝光计的运动线圈仪器,使得仪器的针头参照静态标记移动,以指示所选择的曝光时间的组合 并且孔径尺寸对于计划曝光是令人满意的。

    Abstract: A photographic camera with electronic exposure control and an exposure time indicator. A time scale is arranged along the length of an elongated light source which provides light at uniform intensity and as a function of the brightness condition prevailing at the object to be photographed. The light intensity of the source is varied through a photosensitive element in the electronic exposure control unit. A light attenuating member in the form of a wedge-shaped element in front of the light source extends along the length of the timing scale and provides attenuation which varies continuously in a progressive manner from one end of the wedge-shaped element to the other. A glass member with interference layers and illuminated from an auxiliary light source, is arranged to provide more precise indicating results.
