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 two-dimensional 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. |
