ABSTRACT:
A compact zoom finder suitable for compact cameras, video cameras and the like whose zoom ratio is about 2. While the zoom lens is composed of three units having positive, negative and positive refracting powers in order from an object side, the third unit is preferably composed of an ante-component having a negative refracting power and a post-component having a positive refracting power. In this case, an arrangement is made so that one surface in the ante-component of the third unit comprises a half mirror, and one surface in the post-component is provided with a frame to thereby provide for an albada finder.
