I may be missing something here but I cannot get the zoom to work on my 35-105 lens. It is not in the close focus position (which zooms the lens to 50mm when selected, which is working) but in the non close focus position the combined focus / zoom ring will not slide in and out and feels locked in the 35mm position, focusing ring turns normally.
Never been dropped or mishandled..
Any suggestions as to how to proceed?
