ABSTRACT:
An image sensing apparatus comprising a diaphragm for controlling the amount of incident light, an image pickup element for photo-electrically converting the light incident through the diaphragm, a circuit for supplying an output of the image pickup element to an electronic view finder, a recording circuit for recording the output of the image pickup element, a light measuring circuit for measuring an ambient brightness, and control means for controlling a drive speed of the image pickup element and/or the diaphragm in accordance with the brightness measured by the light measuring circuit, wherein controlling is made such that the depth of field of the object image recorded when shooting is prevented from becoming shallower than the displayed object image in the electronic view finder before the start of shooting.
