|I have had two one touch zooms jam on me, a Tamron and a Vivitar, and they were both impossible to dismantle because of the fault that was jamming them. I sacrificed both lenses in the quest to find out what was wrong. And it was the same thing on both.
The movement of the zoom + focus sleeve is governed by a series of tracks on the inner body, and in the tracks run guides which are tiny screws with plastic / nylon rollers to make the movement smooth. On both lenses a screw / roller had come out and was jammed in the mechanism and no amount of dismantling could get them out.
Both of these lenses had exhibited the same feel of 'slight sticking' when changing direction on the zoom, I guess they were giving notice that a screw was coming loose.
