Real image type viewfinder optical system

摘要

A real image type viewfinder optical system configured so as to allow observation, through an eyepiece, of an image of an object which is formed by an objective, and inverted by image inverting optical members in both a vertical direction and a horizontal direction. This viewfinder optical system uses an objective which is formed as a member integrated with a prism having a first reflecting surface of the image inverting optical members and an eyepiece which is formed as a member integrated with a prism having a final reflecting surface of the image inverting optical members.
