Abstract
The disclosed camera includes a viewfinder which displays a display member representing a preset aperture value in its view field, and is capable of operating in open aperture and stopped down aperture manual exposure modes as well as a shutter priority automatic exposure control mode. A retracting arrangement retracts the display member from the view field in response to a shift either to the stopped down or the shutter priority automatic exposure control mode.
