    • An inverted Galilean finder is composed of an objective lens of a negative power and an eyepiece of a positive power, which are formed from a polystyrene resin by injection molding. The objective lens has a concave surface oriented to the eyepiece, and the eyepiece has a convex surface oriented to the objective lens. The inverted Galilean finder satisfies the following conditions: −0.75≦f1/f2≦−0.60 f1≦−22 −3.2≦f1/d≦−1.5 wherein f1 is a focal length of the objective lens, f2 is a focal length of the eyepiece, and “d” is an on-axis surface distance between the concave surface of the objective lens and the convex surface of the eyepiece. The inverted Galilean finder of the present invention provides a magnification of about 0.6 to 0.8.
