摘要： A camera having a zoom lens. The camera includes a shutter, an aperture and program exposure mode control. The program exposure control includes one or more reference program characteristics representing combinations of shutter speed and aperture corresponding to one or more of a portrait mode, a landscape mode and a close up mode. Each reference program characteristics define a predetermined aperture in a first range from a low shutter speed to a hand-induced vibration limit and defines a different aperture in a second range beyond the hand-induced vibration limit. One of the reference program characteristics is selected, wherein the hand-induced vibration limit is defined in accordance with a focal length of said zoom lens.

摘要： A camera wherein exposure parameters fixed by a program line can be shifted along an exposure value EV line so that exposure parameters for an exposure operation are based on the shifted program line according to the preference of the camera user. The camera has setting means for temporarily changing these exposure parameters at a constant exposure value with respect to the values predetermined by a program line. A counting means counts the number of times that a shutter is released while the program line is shifted in one direction and control means stores the changed values for shifting the program line under certain conditions. In this way a learning function is provided to learn the aforementioned tendency of the user.

摘要： The present invention relates to an optical camera having a zoom function in which a focal length can be varied or the variation is actuated by a focal length changing member, and in particular to a camera in which a focal length is varied through a motor. The optical camera has a zoom lens operable by a rotatable zoom ring for changing the focal length thereof. An automatic focusing operation is effected by a control means when the focal length is changed so that an image of an object viewed through a viewfinder remains in focus. The zoom lens can include a motor and an in-exposure zoom control means can be provided for controlling zooming movement of the lens during an exposure operation.

摘要： A strobe control device for a camera has a light receiving element for receiving and integrating light reflected from a film surface of a film used in the camera. The strobe control device further includes a controller which controls a strobe to emit light. The controller controls the strobe to stop emitting light when the amount of light integrated by the light receiving element reaches a threshold value. The threshold value is adjusted so that the effects on the amount of light received by the light receiving element are canceled when predetermined parameters of a photographing optical path of the camera are changed.

摘要： An information setting and displaying device for a camera, has a ring-like rotary dial rotatably mounted in an adjustable manner on a camera body. A display member includes at least a pair of display sub-areas arranged inside the rotary dial and successively along an inner periphery of the rotary dial. An information setting mechanism changes information in a predetermined order responsive to rotation of the dial. A display control mechanism displays current set information in one of the display sub-areas, and displays proposed information, to be set as the rotary dial rotates, in the direction from the current display sub-area toward another display sub-area.
