A switching variable magnification finder includes an objective lens system having a positive refracting power, an image erecting optical system for erecting an image formed by the objective lens system, and an eyepiece system having a positive refracting power, in which an auxiliary lens system is removably disposed behind the objective lens system so that magnification is varied according to the insertion or removal of the auxiliary lens system. Thus, the switching variable magnification finder allows magnification to be changed without increasing the overall of the finder optical system and moving the objective lens system and its switching mechanism to be simplified.
