Abstract
A changeover mirror is disposed behind a taking lens and is movable between a photographic position on the optical path of the taking lens so as to reflect light passing through the taking lens, on the one hand, and a viewfinder position displaced from the optical path of the taking lens, on the other hand. A conversion lens which is mounted in the camera separately from the changeover mirror, is driven to be positioned on the optical path of the taking lens while the changeover mirror is in the viewfinder position. When the changeover mirror is in the photographic position, a blind member is positioned on the optical path of the viewfinder optics. The blind member shields the photographic optical path from extraneous light that enters through the eyepiece of the viewfinder optics. When the camera is set in a manual focus mode, a split micro prism is positioned in a focal plane of the viewfinder optics. With the split micro prism in place, manual focusing is performed by operating a manual focusing ring.
