Abstract:
A finder optical system is achieved in which object images can be more easily observed. A finder optical system includes an image-erecting member, which erects an object image formed by an objective optical system, provided on an optical path from the object side toward an eyepiece side, wherein the image-erecting member is formed as a penta roof prism provided with a first reflection surface and a second reflection surface, which define a roof reflection surface that reflects an incident light bundle emanated from the object, and the first reflection surface and the second reflection surface are configured as total-reflection surfaces that totally reflect the light bundle including the object image.

Claim (Index 9):
The finder optical system according to  claim 5 , wherein the following condition (7) is satisfied:\n \u03bb i> 500\u2003\u2003(7), wherein \u03bbi designates a peak wavelength, in nanometers, of a light bundle from the information display device.
