ABSTRACT:
A camera including an electronically programmed shutter including improved witches closed during operation of the shutter is provided. The shutter assembly includes an opening member and a locking member carrying shutter blade pivotably mounted to the opening member. Actuation of the opening member triggers closing of the switch which closes the current circuit to an electronic flash device at a maximum predetermined lens opening and initiates the shutter closing. The switches are closed by displacement of a transfer member which is positioned in the locus of movement of the opening member. The position of the transfer member may be set by a switch in the flash device through a linking flash slide or may be changed in response to rotation of the camera focusing element.
