Abstract

Abstract A zoom lens camera has a zoom switch which is operated to drive a zoom lens. A photometric device measures light from an object to drive an aperture in accordance with the result of the photometry that is conducted by the photometric device. The driving of the zoom lens and the driving of the aperture are controlled so that the driving of the zoom lens is temporarily suspended when an instruction is given to drive the aperture. After the aperture has been driven in accordance with the photometry result, the driving of the zoom lens is resumed.
