My cpl is stuck on the end of my lens and i cant get it off due to the fact that its rim is to thin for me to actually apply a great enough pressure for it to turn. I've tried using a cloth on top but that didn't help. I thought about pliers but my lens is to wide and i don't want to damage anything. Anyone run into this problem before?

By on top do you mean the front end of the lens? If not try applying pressure with your hand from the front and turning, you may be able to push hard enough that the filter won't turn but it will unscrew. Failing that get a cable tie around the filter and pull it tight with the pliers and use them to turn it.

Have you tried wearing rubber gloves like the kind you use to wash dishes? Sometimes that works.

Use a rubberband around the filter, that'll help you twist it off.

Also try one of those rubber (pad) jar openers although I think Suzy's idea will give you the best traction.

A filter wrench is the best approach IMHO

Try the rubber glove method...don't be afraid to put a little pressure on the front glass to give you a little more leverage. If that doesn't work, try finding one of those non slip mats...most dollar stores carry them. Place it on a firm, flat surface, place the lens filter down on it, apply moderate downward pressure and twist the lens. Make sure you are infact loosening and not tightening...don't laugh, I've seen it happen. The filter should rotate counter clockwise looking at the lens from the filter end to loosen.

DO NOT use any metal tools to remove it...if all else fails, you can get a plastic/rubber strap wrench from most of your better tool stores that should make quick work of getting it off.

I usually put an ever so slight amount of anti-seize lubricant, applied with a q-tip, on my filter threads to keep this from happening and I've never had one stick.

tried all those things, no luck. The width of the ring is only about 2 millimeters, not much surface to apply torque.

Hmmmm... sorry to hear that. This is sort of from left field, but on the theory that "cold" contracts, what if you took the the lens off and sealed it in a ziploc and then put it in the refrigerator for a little while - not the freezer. Perhaps the thread ring will then contract enough to introduce a little "play" when you try to unscrew it.

The rubber band - thick one is good. Did you use a combination of gloves and rubberband?

An option...and if that doesnt work, heat around the filter CAREFULLY with a hair dryer and continue working it with the rubber gloves, non slip mat method.

If you grasp the filter with only 2 fingers, it will likely distort the filter ring and bind in the lens' threads. Grasp with 3-4 fingers...better yet, use the filter wrench.

Wouldn't this cause the filter to expand in the filter threads on the lens?

I believe the lens that's it mated to has a plastic filter ring if I'm not mistaken...I would imagine it would help loosen it's death grip a bit.

Have you tried whacking it on the counter??? :p
