PURPOSE:To enhance automatic focusing(AF) accuracy at the time of trimming and to obtain a photograph having high image quality even at the time of trimming photographing in a camera capable of trimming. CONSTITUTION:Information on optical zooming in the case of AF is stored in a memory in a photographing lens. Information on trimming (electronic zooming) is similarly stored in the memory, and the defocusing amount of the photographing lens is corrected in the case of performing electronic zooming. For example, focusing detecting areas FA, FA1, and FA2 are all effective when electronic zooming(EZ) is 1.4-power, but it is only the FA that is effective when EZ is 1.7-power. AF action is performed based on such information as is written in the memory. |
