ラ。 A zoom lens consists of a front lens and a variable power lens. During normal shooting, the front lens is driven by a motor for focusing, and during macro photography, the variable power lens is driven within the macro area by a motor. In a camera that performs focusing, the drive control of the front lens and variable power lens is performed, and when the focusing is shifted from focusing by the variable power lens to focusing by the front lens, the variable power lens is moved to a macro area. 1. A camera characterized by comprising a control means for setting a zoom position to a predetermined zoom position or to a predetermined zoom position.
