ABSTRACT:
In an optical lens assembly including front and rear lens systems which are movable relative to each other for focusing or zooming operation, and which include an inner barrel in which one lens system is mounted and an outer barrel in which the other lens system is mounted, there is provided a device for imparting resiliency between the inner and outer barrels which are movable relative to each other. The resilient device may be in the form of a plurality of strips made of resilient material or in the form of an apertured or embossed cylindrical tube, with the resilient device being fixed relative to one of the barrels. The resilient members are made of a lubricant material to impart a degree of lubricity between relatively movable members of the assembly.
