PROBLEM TO BE SOLVED: To provide a zoom finder capable of attaining space-saving and miniaturization of a camera, and reducing load required for a zooming operation. SOLUTION: A lens barrel side slider 15 is held between a projecting part 11 and a torsion bar 14 in the variable power range of a zoom lens and interlocked with an intermediate lens barrel 10. When the lens barrel 10 is moved in the direction of a photographing optical axis Ls, a finder side slider 22 is moved by the lens barrel side slider 15 along the finder optical axis Lf. A lever 26 for moving a front group lens is moved along the finder optical axis Lf and rotated along a stroke adjusting cam groove 25b and around a pin 22d. Front group lenses 27 are moved in the direction of the finder optical axis Lf with a stroke constituted of the combination of the movement and the rotation. On the other hand, a lever 31 for moving a rear group lenses is rotated around a fixed shaft 32, and rear group lenses 33 are moved along the finder optical axis Lf with a stroke defined by the shape of a stoke adjusting cam groove 31c. When the lens barrel 10 is moved to a retreat position, the torsion bar 14 is elastically deformed so as to allow the movement of the lens barrel, and the lens barrel 10 is released from interlock with the lens barrel side slider 15.
