Abstract
A viewfinder mechanism is provided for use with a zoom lens system. The viewfinder mechanism includes a set of pivoting levers driven by the linear motion of the zoom lens. In one particular embodiment, the pivoting levers drive the viewfinder lenses to approximate an apparent zoom corresponding to that performed by the zoom lens system.
