ABSTRACT:
A camera wherein the photographed picture size can be switched and is formed mostly of a magnification variable finder optical system, a photographed picture size switching mechanism and a finder visual field frame switching mechanism. When the picture size is switched by operating the photographed picture size switching mechanism, the finder magnification will be altered to a magnification corresponding to the picture size through a finder cam as operatively connected with the operation and at the same time the finder visual field frame will be also altered in conformity with the finder magnification and picture size. According to this camera, for example, even if the picture frame becomes narrow, the finder magnification will be elevated by switching the picture size and further the image will be made easy to observe by expanding the finder visual field frame.
