Hi there,

if the lens has not been used very much, then the mechanism may actually be stiff and need some lubricating to free it up.

A local camera repair shop can examine it and apply any necessary lubrication to get it moving again.

That is advice not an answer. I was well aware of that possibility, however, The cost would likely exceed the value of the lens. I wanted to know what I could do to repair the item.
