A camera adapted to selectively receive and expose film having different effective film speeds, under both ambient and artificial illumination, the film speed being encoded on film carrying means, includes apparatus to move a filter into the exposure path of a lens axis of the camera when a flash unit is mounted on the camera and apparatus to sense the encoded film speed and to prevent the movement of the filter into the exposure path if film of relatively low speed is in the camera.

Camera diaphragm control apparatus in which slidable diaphragm blades are adjustable by a differential motor to establish and continually maintain an exposure aperture of size related to ambient scene brightness. A linkage, responsive to mounting a flash unit on the camera, connects the differential motor to a focus control member. Through the linkage, the focus control can override the adjustment of the diaphragm by the differential motor, and permit diaphragm adjustment with both ambient light and focus of the camera with distance to the photographic object.

A camera of the type that receives a film cartridge in a cartridge receptacle and secures the cartridge by a door is provided with apparatus for regulating exposure in response to the combination of (1) sensing a film speed indicator carried by the cartridge and (2) closure of the receptacle door. When a cartridge is inserted into the receptacle and a predetermined film speed indicator is present, an indicator sensing member positions an intermediate lever in a ready position to adjust the exposure regulating apparatus. During closure of the receptacle door, a driver element, located to be engaged and moved when the receptacle door is closed further positions the intermediate lever, which in turn adjusts the exposure regulating apparatus.
