<p>The invention relates to an electronic flashgun comprising an arithmetic unit (9) for computing a diaphragm stop number-distance combination, the arithmetic unit comprising a transparent element (11) with a pointer (10). This element is connected to a neutral density filter disc (21) having a variable density and located in front of a light cell (6) provided at the light exit side of the flashgun. The pointer directly indicates a diaphragm stop number on a diaphragm stop number scale (13) of the arithmetic unit.</p> |
