by the way...you can use break liquid from your car it is:
a) a good solvent
b) perfect penetrator through the cracks...

Just use a pipette to put a couple of drops around the ring and put it upside down (front element down) for the liquid penetration.

Good luck!
Brake fluid is highly corrosive and a very effective paint stripper. I would not put it on any part of a lens under any circumstances. But your mileage may vary ?

That is why it is in touch with rubber materials and plastics in your car...
It is a good SOLVENT but not a CORROSIVE liquid...it is a mixture of organic substances there is nothing in there what may trigger corrosion.

Agree that it must be kept away from contact with lens, because it will destroy the coating.

If I remember right you, and looking at your picture, I think you only have to turn it counter clockwise as it's probably simply screwed in.

Look at my first picture. Right under the the front element's ring, there you will see the peripheral threads on which the hood/shade screw.

Let me know how it goes.

Hi, thanks for the quick reply. Yes I have removed the front ring. I was afraid to use force unscrewing it, but from what you say it is a matter of applying some force and unscrewing. Will try it tomorrow hen I get home. Thanks again.

Tried to unscrew. No effect. It stuck like cement.
