摘要： A zoom lens system includes two lens components, and zooming is performed by moving a first lens component. The zooming is performed along a zoom curve such that the first lens component is moved out so that in-focus condition is obtained at a subject distance predetermined with respect to each focal length. As the subject distance, an excess focal length or a subject distance where the far side of the depth of field is the maximum flash reachable distance or a subject distance where the near side of the depth of field is the shortest object distance or a subject distance where the object distance or the magnification is fixed is set according to the purpose.

摘要： An exposure display device for a camera, which can display not only the density of the background to be photographed on a film but also the density of a primary object to be focused with respect to an exposure control value used for exposure control operation. In natural light photography, the brightness of the primary object area at which automatic focus detection is conducted and the brightness of divided object field areas are measured, the density distribution of the primary object area and those of the divided object field areas reproduced on the film are calculated basing on the measurement, and the results are displayed in correspondence to the exposure control value. In flash light photography, the expected brightness of the primary object area and divided object field areas are measured, and the density distribution of the primary object area and object field areas reproduced on the film are calculated and displayed in correspondence to the exposure control value.

摘要： A light measuring device for a single lens reflex camera includes a principal or main mirror capable of dividing light passing through an objective lens towards a finder system and towards a film plane. A submirror is provided behind the main mirror and directs the light passed therethrough towards the film plane for ultimately determining a focusing condition and a measurement of light intensity. A pair of focus detecting photosensor arrays, as well as a spotlight measuring photocell, is arranged relative to the submirror to receive the object light. The auxiliary mirror can be formed with a center portion for reflecting the light through the photocell arrays and a second light-reflecting plane having light diffusive characteristics for directing light for the detection of light measurement.
