Abstract
A camera is provided with a scissors-type iris having apertures of different shapes and areas formed by the pair of blades. In one mode of operation, with a 'flash' setting, a control mechanism automatically adjusts the iris opening in accordance with the focus distance setting and further compensates the iris opening in accordance with an image brightness adjustment. The iris adjustment mechanism automatically is adjusted to certain predetermined positions when the controls are set for other modes of operation, and exposure is then controlled by an electronic shutter timing mechanism which may be varied by a sliding vane brightness adjustment.
