Claims

[Scope of Claim for Utility Model Registration] (1) The incident optical axis is located near and below the optical axis of the photographing optical system of the camera, and a parallax correction mark is provided below the field of view frame. Finder, which is characterized by the fact that (2) The finder according to claim 1, wherein the incident optical path is bent by a mirror or a prism and guided to an eyepiece disposed at the upper rear end of the camera body to form a reverse Galilean type finder. (3) The optical system according to claim 1, wherein the incident optical axis is located directly below the optical axis of the photographing optical system of the camera, and the incident optical path is bent by a mirror or a prism to form a real image type finder with an erect normal image.
