A real image finder system is disclosed. The finder system includes a common objective optical system for forming a real image of an object. A first erecting optical system for erecting an object image formed by the objective optical system, a first eyepiece optical system for observing an image erected by the first erecting optical system, a branch plane which is constructed as one plane of a plurality of reflection surfaces included in the first erecting optical system, and guides a luminous flux from the objective optical system to proceed along a first optical path and/or along a second optical path different from the first optical path, a second erecting optical system which is arranged on the second optical path and erects an object image formed by the objective optical system, and a second eyepiece optical system for observing an image erected by the second erecting optical system.
