Abstract
A camera exposure data setting device for setting exposure data in digital form in response to [on or off] of switches. A first switch actuating member is manually operable for changing mainly an exposure time value and is located at or about the position where a shutter speed setting dial is located in conventional cameras, and a second switch actuating member is manually operable for changing mainly a diaphragm aperture value and is located at a position of the camera opposite from the position of the first switch member with respect to the vertical plane passing through the optical axis of an objective lens. The first switch; actuating member is operated for changing the exposure time value in an exposure time priority automatic exposure control mode and a manual exposure control mode and changing the diaphragm aperture value in a diaphragm aperture priority automatic exposure control mode, and the second switch; actuating member is operated for changing the exposure time value in the exposure time priority automatic exposure control mode and the diaphragm aperture value in the exposure time priority automatic exposure control mode and the manual exposure control mode.
