Mineral PhotographyOlympus SZ-III zoom not working

Please see images. Purchased Olympus SZ-III.


The zoom ring would not turn.


Disassembled. This is the inner portion of the zoom mechanism. The brass portion has an inner tube with lens assembly. The inner lens assembly moves easily.


The outer portion of the brass is machined and appears to be resting on a rail within the aluminum housing. There are springs behind this rail attaching the brass to the aluminum. I assume that this is meant to slide up and down on the aluminium rail. It does not move at all. Is there something I am missing? I cannot free it with application of pressure. may be that grease has set / dried to an extent that it will take significant force to free. But I don't want to take a hammer to it.


Any thoughts / suggestions?


Thanks!!!!!

Pack all the pieces up in a well padded box, and send to a well qualified microscope maintenance facility.

It is meant to slide freely, perhaps the previous person lubricated this mechanism with a lubricant that contained sulphur (sometimes this is an additive in EP oils and greases) this can react with brass and causes it to seize.

As to how you can free the mechanism I can't help except by saying DO NOT use a hammer. Should you manage to free it up make sure you use the correct lubricant, be warned it costs a fortune. There was a thread a while back dealing with microscope lubricants.
