A photographic camera including a plurality of focal length settings, a chargeable flash device, and a mechanism for indicating an exposure ready condition at a predetermined state of charge, is characterized by means responsive to the focal length setting for adjusting the predetermined state of charge at which the ready condition is indicated. The state of charge is more complete at longer focal lengths to ensure sufficient illumination and is less complete at shorter focal lengths to reduce wait time. According to one feature of the invention, the camera includes contact elements having a plurality of discrete positions, one each representing a different focal length, and the predetermined state of charge is adjusted depending on the position of the contact elements. The flash ready condition may be signaled by a number of different mechanisms including, for example, flash ready lights, the extinguishment of exposure wait lights, and the release of actuation interlocks.
