Abstract

Cable release arrangement which is connectable to the shutter of a camera, comprising two flexible power transmitting members which are provided, at one corresponding end, with an actuating handle formed as a common housing, and, at the other corresponding end, with a threaded connection, one transmitting member being used to release the shutter and the other transmitting member being used to actuate the diaphragm blades and/or the shutter segments for the purpose of viewing through the camera shutter, wherein the transmitting member for effecting shutter release is actuatable by direct finger pressure upon an axially displaceably mounted push rod therefor, whereas the transmitting member which acts upon the diaphragm blades and/or the shutter segments is actuatable indirectly by way of a switching device which progressively displaces its axially displaceably mounted push rod, and wherein the corresponding end pieces of the two transmitting members which guide the rods respectively, are combined in said housing which accordingly serves to accommodate the switching device and also fulfils the function of such actuating handle; PA1 preferably with the switching device being separatel…
