Zoom lens bearing camera

Abstract

A zoom lens bearing camera comprises a zoom lens having a full-aperture F number which changes as a zoom focal length is changed, the zoom focal length being controllable to a desired value through electrical driving, a ranging unit for measuring a distance to a subject, a metering unit for measuring brightness of a scene containing the subject, an electronic flash unit for supplying as an auxiliary light source to the subject, a sensitivity detecting unit for detecting a film exposure sensitivity, a first data table in which optimum zoom focal lengths respectively corresponding to various subject distances are set, a second data table in which optimum zoom focal lenghts respectively corresponding to the various subject distances are set according to a range of the electronic flash, and a zoom focal length determining unit for determining the zoom focal length corresponding to the distance to the subject by selecting the first data table when a quantity of exposure obtained based upon the brightness of the scene measured by the metering unit, the film exposure sensitivity detected by the sensitivity detecting unit, and a full-aperture F number in a selected zoom focal length is not less than a setting value, while selecting the second data table when the quantity of exposure is less than the setting value.
