Abstract
A zoom lens mount in which all adjustments for variation of focal length and for focusing at all focal lengths as well as marco-focusing can be accomplished by manipulation of a single external operating ring. Movements are smooth from one position to another, eliminating or reducing the danger of jamming which has occurred with some prior constructions. Focal length is adjusted by axial displacement of the operating ring, and focusing by rotation of the operating ring. In the wide-angle position, marco-focusing can also be accomplished with the same operating ring.
