ABSTRACT:
In the disclosed finder, a half transparent surface positioned behind a photographic lens splits off part of the light passing through the photographic lens to a first image plane at a position equivalent to a focal plane of the photographic lens. At least two lens components refocus light from the first image plane onto a second image plane conjugate to the first one. An image on the second plane is observed through an eyepiece. An even number of reflective surfaces, but not less than four, including the half transparent surface, are arranged in an optical path from the photographic lens to the eyepiece and at least one of these reflective surfaces lies between the two lens components. A decrease in the physical length of the finder and an increase in the image magnification are achieved.
