    摘要： A camera having, in addition to a real focal length photographing mode, a pseudo focal length photographing mode, namely, a photographing mode in which a part of a photographed image frame of a film is printed at an enlarging ratio different from an ordinary enlarging ratio to obtain a print as if it had been photographed using a telephoto lens. It is provided with means for recording photographing mode information on a frame of a film when the pseudo focal length photographing mode is selected, and a control means which brings a flash light emitting device into an operable condition in response to the selection of the pseudo focal length photographing mode and which actuates the flash light emitting device in synchronism with release of the shutter. An optical axis of a photographing lens and a flash emission tube are spaced from each other, and the pseudo focal length photographing mode can be selected only when a negative film is loaded in the camera.

    摘要： A photographic camera having a photographic lens system freely settable to various focal lengths, an openable and closable lens cover disposed in front of the photographic lens system, an opening and closing mechanism for the lens cover, a motor for providing kinetic energy for the focal length changeover operations of the photographic lens system and also for the opening and closing operations of the lens cover, and a drivable cylinder capable of transmitting the kinetic energy from the motor to the photographic lens system and to the opening and closing mechanism in the form of a mechanical displacement. The opening and closing mechanism opens the lens cover by utilizing a mechanical displacement from a home position to an intermediate position of the drivable cylinder and closes the same by utilizing a mechanical displacement from the intermediate position to the home position of the drivable cylinder, and further changes over a focal position by utilizing mechanical displacements reversibly between the intermediate position and an end position of the drivable cylinder.

    摘要： A camera capable of identifying photographing conditions causative of red-eye effect making the eyes of human pictures in a flash-photographed picture come out red, and recording the identified photographing conditions in an external memory provided on a film cartridge loaded thereon. The camera recognizes the possibility of occurrence of red-eye effect on the basis of the focal length of the camera lens, the object distance, the distance between the optical axis of the camera lens and the light source of the flash light device and the object brightness. When the photographing conditions are identified to be causative of red-eye effect, a warning is displayed and flash photographing is forbidden. When photographing operation is carried out under photographing conditions liable to cause red-eye effect, information about the exposed film including the photographing conditions is recorded in the external memory to enable the subsequent developing and printing processes to correct the photograph with reference to the information.

    摘要： There is disclosed a device for correcting and compensating variations of the back focal length caused by temperature changes in a photographic lens system which incorporates at least one lens component made of a plastic material. The device includes a lens drive which axially moves the lens system to obtain a fully focused image of an object to be photographed, and a temperature sensor which senses surrounding temperature conditions and produces output signals representing the sensed temperature condition. A lens control is also provided in the device, and functions in response to the output signals from the temperature sensor to control the lens drive in a manner to compensates any temperature-related variation of the back focal length of the lens system.
