A camera with a multi-zone focus detecting device has an objective lens mounted on a camera. An image formed by the objective lens is divided into a plurality of zones. In each zone, a focusing condition is detected based on the image formed by the objective lens so as to produce a plurality of focusing condition data. Based on the result of the focusing conditions, one zone is selected. Furthermore, a light which has passed through the objective lens is measured separately in each zone so as to produce a plurality of measured light data. Based on a focusing condition data obtained from the selected zone, the objective lens is driven to an infocus condition. When the objective lens is driven to the infocus condition, a measured light data obtained from the selected zone is used for calculating exposure data with which the exposure is controlled.

A camera with a multi-zone focus detecting device comprising: an objective lens mounted on a camera; means for detecting focusing conditions in a plurality of zones in a photographing field to be photographed, based on light which has been passed through said objective lens so as to produce a plurality of focusing condition data; means for selecting one zone based on the result of the focusing conditions, provided that a certain condition is satisfied; means for detecting whether or not said selecting means is selecting one zone; means for measuring light in an area corresponding to said selected zone based on light which has passed through said objective lens as a spot light data; means for measuring light in said image as an average light data; means for choosing said spot light data when said detecting means detects that one zone is selected, and said average light data when said detecting means detects that no zone is selected; and means for calculating exposure data based on said chosen data.
