View finder optical system |
摘要 |
A view finder optical system suitable for use in a single or twin lens reflex camera, using an image erecting-and-reflecting optical element. This optical element functions to change the image to be photographed appearing on the focusing plate of the camera to an erect real image which stands at a proper distance from the eyepiece of the camera. This makes it possible to increase the magnification of the view finder as much as required simply by using a short focal length eyepiece.
