| I have 28-90 standard canon lens and UV filter got stuck in it. when I try hard, it hear some thread skip sound from the lens. I am not sure if I break the lens when I try hard. is there any way to take out the UV filter? |

this is what you do...
you take a sledge hammer and hit it perpendicular to the lens near the area wher it is stuck

You could always try the "heat it up" trick, either by trying to run the ring area under hot water or using flame of some kind. that will expand and loosen the filter ring some to try to get just the glass out or the whole filter. worh a shot.
or a pair of needle nosed pliers to get a hold of the edge of the ring.

Try holding the lens pointed toward the floor while rubbing an ice cube around the rim of the filter, then quickly try unscrewing it before it heats back up. If you have a rubber pot pad, you might try putting the pad on the filter, then using the palm of your hand and pressing evenly all around toward the lens, see if it will unscrew.
They make special wrenches for removing stuck filters like that. In a pinch, a hose clamp from an auto parts store around the edge of the filter can be used to get a better and more even grip on the filter.
A lot of the trick is to not distort the ring while trying to unscrew it. Try to spread the turning force all around the entire outside of the ring.
A small drop of "W D 40", applied with a tooth pick at the edge of the threads and allowed to soak in for a while may help if you get desperate. The lube can be cleaned off with alcohol later.
If you do decide to try heating it, a hair dryer would work for that. Then while it is hot, use a washcloth dampened with ice water on your palm and press and turn.

One way to increase your grip on the filter without pinching it too tightly is to wrap a rubber band around it. Might just help, although if the whole unit has been dropped, for example, and the thread damaged, then it would be extremely difficult to unscrew.

why don't you just leave it on? I have a uv on every lens I have ever owned, they don't take away from an image and keep the actual lens clean.

| If you still have no luck, you could try cutting it off with a pair of side-cuts (aka wire cutters). You could nip a bit away and see if it gets easier. If not, nip more away. |

| Homebrew suggestions are great and all, but... just get a set of filter wrenches. |

No need for any specialized equipment. Either of the following will work.
1) wide rubber band (usually found around broccoli at the grocery store)
or
2) Shelf liner material (the rubbery type)
Either of these things allows you to get the grip that you need to be able to turn the filter without slippage.

or... spray a little wd-40 on a rag and wipe around area where the filter mates with the lens. let sit a few minutes and it should come right off.

Had the same problem myself. Keep calm. Get a good grip and you will succeed. Luckely it's not a pol filter. That's keep turning and turning an turning and......

Sure... until you get two filters stuck together. You know - when they come off the camera easily, but they're still too small to hold. It's even better when you have stepping rings in the mix.
Sorry... wouldn't give up my filter wrenches for the world. |

In that situation, I'd put the works back on the lens and work from the outside in.
