Hold camera facing down and give a gentle squirt or two with WD40. Wait 10 minutes or so and try unscrewing. Wash both filters in soapy water (dishwash is fine) after this, rinse well and dab dry with a microfibre cloth.

I second this method. Let the WD20 seep into the threads for 10 to 15 minutes. Use very little. I mean very little. You don't want it to get a lot on the filter. And you don't need a lot of the stuff. Did I say very little? VERY LITTLE

Do NOT grab the filter with a finger on each side. That just distorts the filter ring enough to make it impossible to turn. DO grab the filter ring at one spot using thumb and forefinger. Now turn counter clockwise. It should come undone rather easily.

So many good responses...will we ever know if the OP got it un-together?

Well, he hasn't logged in to his account in 2 months, so it seems the mystery will remain.

I guess he succeeded but then by trying to re-attach both filters he somehow landed in between, thus not being able to answer.....

I hope it makes sense (not the mess up, my typing. English is not my native language)

(Lens)
(Uv-filter)
(ND-filter)

To avoid sticky filter threads in the future, use a pencil! I read about this trick sone time ago. I simply run a pencil tip around the thread of the filter (as opposed to that of the camera), then using a blower, just blow off any possible residue around the thread from the lead pencil and that's it. I've never had a sticky thread since!

Running a bar of soap or a wax candle on the threads works too, but not as good as graphite.

Gentlemen (and others !

Thank you.

Your instructions are duly noted. Unfortunately, the 'RED' key on my keyboard no longer works.

Yes. Try putting tips of thumb and index finger on opposite sides while gripping bottom filter with other thumb and index finger and use a downward and turning force instead of a side pinching force. Or a filter wrench.
