Abstract
The invention is to provide a zoom finder which serves to make the size of camera compact and to reduce the mechanical loss in shifting the lenses to vary magnification of field view of the finder. A zoom finder of the invention including an intermediate lens barrel movable from a retracted position to a variable magnification section, capable of varying magnification of field of view by shifting a first lens and a second lens in association with the movement of the intermediate lens barrel, comprises a moving member guided by a guiding means disposed along an optical axis of the finder optical system and interlocked with the intermediate lens barrel, a first lever pivotally mounted on the moving member; a first cam engaging the first lever to rotate it in association with movement of the moving member; a first supporting member for supporting the first lens engaging a slot formed in the first lever; a second lever engaged with the moving member rotatable in association with the movement of the moving member; and a second lens supporting member engaging a cam slot formed in the second lever; wherein the first lens is shifted by both the rotation and the movement of the first lever and simultaneously the second lens is shifted by the rotation of the second lever, which are caused in association with the movement of the moving member, and the interlocking mechanism is disabled with its interlocking function when the intermediate lens barrel moves into the retracted position from the variable magnification section.
