Camera including a device for controlling the photographing optical systems to prevent obscuring of an image in the finder optical system

摘要

An improved camera includes a photographing optical system and a finder optical system, existing independently from each other. In order that a finder observation image will not be obstructed by a camera lens, the camera comprises a driving circuit for respectively driving the photographing optical system and the finder optical system, and an optical system control circuit for controlling the photographing optical system in a manner such that the finder optical system will not be obstructed by the photographing optical system.
