ABSTRACT:
A shutter and flash synchronization assemblage comprising a flash circuit board having a shutter-flash synchronization contact, a shutter blade supported for movement between a lens covering position and a lens uncovering position, and an electrically conductive return spring urging the shutter blade to be returned to the lens covering position and connected with the flash circuit board to permit flash illumination to be triggered when the shutter blade is moved to the lens uncovering position, is characterized in that the shutter blade is electrically non-conductive, and the return spring has a synchronization portion arranged for the shutter blade to move the synchronization portion against the shutter-flash synchronization contact to trigger flash illumination when the shutter blade is moved to the lens uncovering position.
