PROBLEM TO BE SOLVED: To provide a variable magnification finder for adjusting diopter for easily adjusting the diopter of a finder objective lens system with a small-sized and simple constitution. SOLUTION: An eccentric pin supporting part 6c is provided at a third finder lens supporting part 6, to which an eccentric pin 7 is pressedly inserted. The eccentric pin 7 has an eccentric step part at its rotary tip, the step part is pressedly contacted to a side face of a spiral cam part 8. By rotating a head part of the eccentric pin 7, a distance from the side face of the spiral cam part 8 to a center of the eccentric pin 7 can be adjusted, thereby the diopter can be adjusted by changing a stipulated distance between a second finder lens 2 and the third finder lens 3 in zooming.
