摘要： A changeable magnification inverted Galilean finder includes, in succession from the object side, an objective lens group having a negative refractive power, and an eyepiece of positive refractive power disposed at a predetermined distance from the objective lens group. The objective lens group has a first objective lens for low magnification and a second objective lens for high magnification. The first objective lens for low magnification has a first negative lens component having a predetermined negative refractive power. The second objective lens for high magnification has a negative refractive power smaller than the refractive power of the first objective lens for low magnification, and has a second negative lens component and a positive lens component added on the object side of the second negative lens component. A low magnification state in which the objective lens for low magnification is disposed on the same optic axis as that of the eyepiece and a high magnification state in which the objective lens for high magnification is disposed on the same optic axis as that of the eyepiece are selectively constructed.
