Abstract
An automatic exposure camera in which any one of four modes, specifically, an aperture-priority automatic exposure mode, a shutter-speed-priority automatic exposure mode, a programmed automatic exposure mode and a manual exposure mode, can be readily set with reduced danger of improper selection. An automatic/manual switch is operated in association with a lens aperture ring to select one of an automatic aperture mode and a manual aperture mode for a lens of the camera. A mode A counter responds to the output of the automatic/manual switch to be made active when the automatic aperture mode is selected, and a mode M counter responds to the automatic/manual switch to be made active when the manual mode is selected. The output of one of the mode A counter and the mode M counter is selected for counting signals from the up or down switch to thereby set the exposure mode according to a count value so obtained.
