摘要： A camera includes an object distance detecting device. The detected object distance can be used to calculate magnification which, in turn, can be used to determine an aperture value. The object distance detecting device can be selectively operated depending on, for example, whether flash lighting is being used.

摘要： An camera system includes a body and an accessory which is attachable to the camera body. A controller is provided in the camera body for controlling camera function. And an operable switch is also provided in the camera body. A function data concerning with camera function is sent from the accessory to the camera body. The camera body receives the function data and determines in response to the operation of the operable switch whether or not the controller controls camera function based on the received function data. According to the camera system, it is possible to enable or disable the camera function depending on the accessory by simple operation with the accessory attached to the camera body.

摘要： A camera according to the present invention comprises a taking lens whose focal length is variable. A focal length thereof is determined based on a subject distance measured by a distance measuring circuit and a relation between a subject distance and a focal length previously stored in a memory or according to a manual operation. The relation stored in the memory is changed based on a focal length determined.

摘要： In a flash light amount control device capable of operating according to multiple methods, the flash light control method alternates according to the detected AF mode setting, the camera panning status, or the reliability of the detected object distance. For example, if AF lock is on, control is performed by flash light adjustment, but if AF lock is not on, control is performed by flashmatic. If panning is performed after AF lock, the method of control alternates between flash light adjustment and flashmatic in response to the amount of panning movement.

摘要： A focus detection condition display device suitable for use in a camera provided with an electronic viewfinder. The pattern signal corresponding to a focus detection zone on which focus detection is conducted by a focus detecting system is superimposed on the video signal of the object field and said signal is output to an electronic viewfinder. When the focus detection has become impracticable for such reason as lack of contrast of the object field, or focusing has become impracticable because of the object coming too close to the camera, an alarm is issued by the pattern corresponding to a focus detection zone displayed on the electronic viewfinder displaying in a manner different from that ordinarily used.

摘要： A pseudo focal length camera which takes a photograph using an optical system of a single focal length. A printed photograph has a feature similar to that obtained by taking a photograph using an optical system comprising a plurality of photographing lenses each having a different focal length. Information indicating an image forming area corresponding to a designated pseudo focal length is recorded on a film when a photograph is taken and a printing is carried out based on the information. The view finder optical system includes a liquid crystal display for displaying the size of an image forming area which changes according to a magnification corresponding to each pseudo focal length. After the image forming area is determined by designating a pseudo focal length, the first switch is turned on by the depression of the release button in the first state. As a result, the lens of the view finder optical system is driven and consequently, the image corresponding to the determined image forming area appears in the whole area of the view finder. An exposure is effected by the depression of the release button to the second stage.
