Stuck filter
Jun 12, 2014 14:34:26 #
I bought an Olympus OM 4 in very nice condition. No dents or scratches, just a little worn paint here and there. The seller included "for free", and it may have been for the price he charged, a 28mm Zuiko with a really, really stuck UV filter. All this he disclosed.
The lens looks to be in very nice shape, except for the filter. Some hamhanded putz apparently use brute force. I've tried pressing it against a rubber shoe heel, using kitchen lid remover pads, etc. I'll probably try freezing the whole thing to see if thermal "shrinkage" would work in my favor.
Any suggestions? I don't care if the filter is destroyed, but the lens looks really clean - snappy diaphragm, etc.

Suggest you use the search function and search for "stuck Filter." I seen a full page of results.
Good luck.
Good luck.

From previous UHH postings.
Other ideas: rubber jar cap remover, filter wrench, the heel of a man's shoe, an electrical cord. You get the idea - you need a good gripper.
Another idea. Carefully hacksaw through the filter ring. That will relieve the pressure and make removal easier.

Is the leading edge of filter knurled?
If so, I have removed a stuck lens by gently-but-firmly pressing entire camera with filter squarely down on a piece of pine board (not too soft to cut & spin, nor too hard to slip & spin) and gently-but-firmly twisting camera body (in correct direction), so filter knurling (teeth) remains imbedded in wood. Board must be anchored, so filter & wood do not turn with camera.

Thanks, worth a try.

I haven't tried the filter wrenches yet, I can't find mine. Part of the problem is that the diaphragm ring is perhaps 3/16" from the front of the lens, so there's little space to grip the lens barrel other than with a filter wrench without applying force to the diaphragm mechanism.
I may freeze the whole shebang to see if the lens and filter would contract differentially. The filter is aluminum, the lens I don't know. Brass I would hope.
The hacksaw suggestion sounds more and more interesting.

Give it a good soaking with some WD 40 and let it sit overnight.

take it to a camera shop and let them do it - if they break it, they can replace it...

I'm tending in that direction. Wings Camera here in the Atlanta area specializes in used gear. Mike is an old hand and I'd trust to know what to do.

Hair dryer to heat up the ring and expanded it. Then use a rag to grasp it and turn it. Make sure to point the heat up away from the base of the lens where the electronic is. I had to do this last year when I put a lens on in 5 degree weather and tried to take it off later in my office after the lens warmed up.

google spanish windlass works on all sorts of circular stuck stuff.

Interesting. But I don't see how this could translate into a circular force as would be needed for unscrewing something....
But thanks! UHH comes through, as always!

This may be overly simplistic, but would a jar opener help, the sort of thing one uses as one's hands get older and less strong?
