ABSTRACT:
A mechanism for controlling synchronized operation of a zoom lens includes a cam mechanism defining a first camming surface and a supplementary camming surface for each of the lens components to be moved. A lens holder has an engagement member extending therefrom into abutment with the first camming surface and a spring member operatively interposed between a second engaging member and the lens holder urges the second engaging member against the supplementary camming surface thereby to insure that the first engaging member remains in abutment with the first camming surface to effect desired axial displacement of the lens component.
